The invention relates to a device for the generative production of at least one component region of a component, in particular of a component of a turbomachine, as well as a method for the generative production of at least one component region of a component, in particular a component of a turbomachine according to the preamble of claim 13.
Verfahren und Vorrichtungen zur Herstellung von Bauteilen sind in einer großen Vielzahl bekannt. Insbesondere sind generative Fertigungsverfahren (sog. Rapid Manufacturing- bzw. Rapid Prototyping-Verfahren) bekannt, bei denen das Bauteil durch pulverbettbasierte, additive Ferti- gungsverfahren schichtweise aufgebaut wird. Vorwiegend metallische Bauteile können beispielsweise durch Laser- bzw. Elektronenstrahlschmelz- oder -sinterverfahren hergestellt werden. Dabei wird zunächst schichtweise mindestens ein pulverförmiger Bauteilwerkstoff auf eine Bauteilplattform im Bereich einer Aufbau- und Fügezone der Vorrichtung aufgetragen. Anschließend wird der Bauteil Werkstoff schichtweise lokal verschmolzen und/oder versintert, in- dem dem Bauteil Werkstoff im Bereich der Aufbau- und Fügezone Energie mittels wenigstens eines Hochenergiestrahls, zum Beispiel eines Elektronen- oder Laserstrahls zugeführt wird. Der Hochenergiestrahl wird dabei in Abhängigkeit einer Schichtinformation der jeweils herzustellenden Bauteilschicht gesteuert. Nach dem Verschmelzen und/oder Versintern wird die Bauteilplattform schichtweise um eine vordefinierte Schichtdicke abgesenkt. Danach werden die genannten Schritte bis zur endgültigen Fertigstellung des Bauteils wiederholt. Methods and apparatus for manufacturing components are known in a wide variety. In particular, generative manufacturing methods (so-called rapid manufacturing or rapid prototyping methods) are known in which the component is built up in layers by means of powder-bed-based, additive manufacturing methods. Primarily metallic components can be produced, for example, by laser or electron beam melting or sintering methods. In this case, at least one powdered component material is initially applied in layers to a component platform in the region of a buildup and joining zone of the device. Subsequently, the component material is locally melted and / or sintered layer by component in the material in the assembly and joining zone energy by at least one high energy beam, for example, an electron or laser beam is supplied. The high-energy beam is controlled in dependence on a layer information of the component layer to be produced in each case. After fusing and / or sintering, the component platform is lowered in layers by a predefined layer thickness. Thereafter, the said steps are repeated until the final completion of the component.
Aus dem Stand der Technik sind insbesondere auch generative Herstellverfahren für die Herstellung von Bauteilen einer Strömungsmaschine, wie beispielsweise von Bauteilen eines Flugtriebwerks oder einer Gasturbine bekannt, z.B. das in der DE 10 2009 051 479 AI beschriebene Ver- fahren bzw. eine entsprechende Vorrichtung zur Herstellung eines Bauteils einer Strömungsmaschine. Bei diesem Verfahren wird durch schichtweisen Auftrag von mindestens einem pulverförmigen Bauteil werkstoff auf einer Bauteilplattform im Bereich einer Aufbau- und Fügezone sowie schichtweises und lokales Schmelzen oder Sintern des Bauteilwerkstoffs mittels im Bereich der Aufbau- und Fügezone zugeführter Energie ein entsprechendes Bauteil hergestellt. Die Zufuhr der Energie erfolgt hierbei über Laserstrahlen, wie beispielsweise C02-Laser, Nd:YAG-Laser, Yb-Faserlaser sowie Diodenlaser, oder durch Elektronenstrahlen. Bei dem in der DE 10 2009 051 479 AI beschriebenen Verfahren wird weiterhin das erzeugte Bauteil bzw. die Aufbau- und Fügezone auf eine Temperatur knapp unterhalb des Schmelzpunkts des Bauteilwerkstoffs mittels eines Zonenofens erwärmt, um eine gerichtet erstarrte oder einkristalline Kristallstruktur auf- rechtzuerhalten . In particular, generative production methods for the production of components of a turbomachine, such as, for example, components of an aircraft engine or a gas turbine are also known from the prior art, for example the method described in DE 10 2009 051 479 A1 or a corresponding apparatus for the production a component of a turbomachine. In this method, by coating layers of at least one powdered component material on a component platform in the region of a buildup and joining zone as well as layered and local melting or sintering of the component material by means of supplied in the field of buildup and joining zone energy produced a corresponding component. The energy is supplied by laser beams, such as CO 2 lasers, Nd: YAG lasers, Yb fiber lasers and diode lasers, or by electron beams. In the method described in DE 10 2009 051 479 A1, furthermore, the component produced or the assembly and joining zone is heated to a temperature just below the melting point of the component material by means of a zone furnace in order to maintain a directionally solidified or monocrystalline crystal structure.
Aus der DE 10 2006 058 949 AI ist ebenfalls eine Vorrichtung und ein Verfahren zur schnellen Herstellung und Reparatur von Schaufelspitzen von Schaufeln einer Gasturbine, insbesondere eines Flugtriebwerks bekannt, wobei eine induktive Heizung zusammen mit Laser- oder Elektro- nenstrahlsintern eingesetzt wird. From DE 10 2006 058 949 AI an apparatus and a method for the rapid production and repair of blade tips of blades of a gas turbine, in particular an aircraft engine is also known, wherein an inductive heating is used together with laser or electron nenstrahlsintern.
Eine induktive Heizung des herzustellenden Bauteils im Zusammenhang mit der generativen Herstellung eines Bauteils mit Hilfe von selektivem Laserschmelzen ist auch in der EP 2 359 964 AI beschrieben. An inductive heating of the component to be produced in connection with the generative production of a component by means of selective laser melting is also described in EP 2 359 964 A1.
Die WO 2008/071165 AI beschreibt wiederum eine Vorrichtung und ein Verfahren zur Reparatur von Turbinenschaufeln von Gasturbinen mittels Pul Verauftrags schweißen, wobei für die Auftrags schweißung eine Strahlungsquelle, wie ein Laser oder ein Elektronenstrahl, Verwendung findet. Zugleich wird über eine Induktionsspule eine Heizvorrichtung zur Beheizung der zu repa- rierenden Schaufel bereitgestellt. WO 2008/071165 Al again describes welding a device and a method for repairing turbine blades of gas turbines by means of powder application, wherein a radiation source, such as a laser or an electron beam, is used for the deposition welding. At the same time, a heating device for heating the blade to be repaired is provided via an induction coil.
Die DE 10 2012 206 122 AI beschreibt eine Vorrichtung zur generativen Herstellung von Bauteilen mittels einem Laserpulverauftragsschweißen und/oder einem selektiven Bestrahlen eines Pulverbetts, wobei die Vorrichtung mindestens eine relativ zu einem oder mehreren Pulver- betträumen beweglich angeordnete Induktionsspule aufweist. Die Induktionsspulen sind dabei entlang separat ausgebildeter Schienenanordnungen linear verfahrbar. Durch die lokale und individuell auf die Geometrie des herzustellenden Bauteils angepasste induktive Erwärmung des Bauteils ist es möglich, dass Heißrissbildungen, insbesondere bei der Verwendung von Hochtemperaturlegierungen für die generative Fertigung, bei der Herstellung des Bauteils zuverlässig verhindert werden. Als nachteilig an den bekannten Vorrichtungen, die bewegliche Induktionsspulen umfassen, ist aber der Umstand anzusehen, dass hierfür ein zusätzlicher apparativer Aufbau wie zum Beispiel zusätzliche Schienenanordnungen notwendig sind. Dadurch verteuert sich die Vorrichtung und eine nachträgliche Umrüstung derartiger Vorrichtungen ohne beweglichen Induktionsspulen auf Vorrichtungen mit entsprechenden Induktionsspulen ist oftmals nicht oder nur mit hohem kon- struktiven Aufwand möglich. DE 10 2012 206 122 A1 describes a device for the generative production of components by means of laser powder deposition welding and / or selective irradiation of a powder bed, wherein the device has at least one induction coil movably arranged relative to one or more powder bed spaces. The induction coils are linearly movable along separately formed rail arrangements. Due to the local and individually adapted to the geometry of the component to be produced inductive heating of the Component, it is possible that hot cracking, especially when using high-temperature alloys for additive manufacturing, are reliably prevented in the manufacture of the component. As a disadvantage of the known devices comprising movable induction coils, but the fact is to be considered that this additional equipment structure such as additional rail arrangements are necessary. As a result, the device becomes more expensive and subsequent retrofitting of such devices without movable induction coils on devices with corresponding induction coils is often impossible or only possible with a high degree of construction effort.
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung der eingangs genannten Art zu schaffen, die einen vereinfachten konstruktiven Aufbau aufweist und eine relativ einfache Nachrüstung mit mindestens einer verfahrbaren Heizvorrichtung ermöglichen. Des Weiteren ist es Aufgabe der vorliegenden Erfindung, ein Verfahren der eingangs genannten Art bereitzustellen, welches konstruktiv einfach realisierbar ist. Object of the present invention is therefore to provide a device of the type mentioned, which has a simplified structural design and allow a relatively simple retrofitting with at least one movable heater. Furthermore, it is an object of the present invention to provide a method of the type mentioned, which is structurally easy to implement.
Diese Aufgaben werden erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1 zur generativen Herstellung zumindest eines Bauteilbereichs eines Bauteils, durch ein entsprechendes Verfahren mit den Merkmalen des Patentanspruchs 13 sowie einen Beschichter zur Verwendung in einer Vorrichtung zur generativen Herstellung zumindest eines Bauteilbereichs eines Bauteils mit den Merkmalen des Anspruchs 18 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den jeweiligen Unteransprüchen angegeben, wobei vorteilhafte Ausgestaltungen der Vorrichtung als vorteilhafte Ausgestal- tungen des Verfahrens sowie des Beschichters und umgekehrt anzusehen sind. These objects are achieved according to the invention by a device having the features of patent claim 1 for the generative production of at least one component region of a component, by a corresponding method having the features of patent claim 13 and a coater for use in a device for the generative production of at least one component region of a component Characteristics of claim 18 solved. Advantageous embodiments with expedient developments of the invention are specified in the respective subclaims, wherein advantageous embodiments of the device are to be regarded as advantageous embodiments of the method and of the coater and vice versa.
Ein erster Aspekt der Erfindung betrifft eine Vorrichtung zur generativen Herstellung zumindest eines Bauteilbereichs eines Bauteils, insbesondere eines Bauteils einer Strömungsmaschine. Die Vorrichtung umfasst dabei mindestens einen Beschichter zum Auftragen von mindestens einer Pulverschicht eines Bauteilwerkstoffs auf mindestens eine Aufbau- und Fügezone mindestens einer absenkbaren Bauteilplattform, wobei der Beschichter relativ zu der Bauteilplattform bewegbar ist. Zudem umfasst die Vorrichtung mindestens eine Strahlungsquelle zum Erzeugen wenigs- tens eines Hochenergiestrahls, mittels welchem die Pulverschicht im Bereich der Aufbau- und Fügezone lokal zu einer Bauteilschicht verschmelzbar und/oder versinterbar ist. Des Weiteren ist an dem Beschichter mindestens eine Heizvorrichtung angeordnet. Durch die Anordnung der Heizvorrichtung an dem Beschichter ist es möglich, die Pulverschicht des Bauteilwerkstoffs vor, während und/oder nach der Belichtung mittels der Strahlungsquelle in diesem Bereich zu erwärmen. Aufgrund dieser Erwärmung mittels der Heizvorrichtung werden zuverlässig, insbesondere bei der Verwendung von Hochtemperaturlegierungen als Bauteilwerkstoff, Heißrissbildungen vermieden. Da die Heizvorrichtung an dem Beschichter angeordnet ist, kann zunächst auf zusätzliche Verfahreinheiten zur Bewegung der Heizvorrichtung im Bereich der Aufbau- und Fügezone des Bauteils verzichtet werden. Die Heizvorrichtung kann an dem Beschichter nicht- verfahrbar angeordnet sein, so dass diese durch die Bewegung des Beschichters entlang bzw. über die Aufbau- und Fügezone der Bauteilplattform bewegt wird. Dadurch ist ein einfacher konstruktiver Aufbau der Vorrichtung insgesamt gegeben. Zudem können bereits vorhandene Vorrichtungen zur generativen Herstellung von Bauteilen mit einer entsprechenden Heizvorrichtung, die an dem Beschichter angeordnet wird, nachgerüstet werden. Diese wird dann mit dem Beschichter über eine entsprechende Verfahreinheit des Beschichters über die Aufbau- und Fügezone der Bauteilplattform bewegt. Unter den Begriffen„angeordnet" oder„Anordnung" ist zu verstehen, dass die Heizvorrichtung direkt oder indirekt mit dem Beschichter verbunden werden kann. Beispielsweise ist eine mechanische Verbindung mit dem Beschichter möglich. A first aspect of the invention relates to a device for the generative production of at least one component region of a component, in particular of a component of a turbomachine. The device comprises at least one coater for applying at least one powder layer of a component material to at least one assembly and joining zone of at least one lowerable component platform, the coater being movable relative to the component platform. In addition, the device comprises at least one radiation source for generating less at least one high-energy beam, by means of which the powder layer in the region of the assembly and joining zone is locally fusible to a component layer and / or sintered. Furthermore, at least one heating device is arranged on the coater. The arrangement of the heater on the coater, it is possible to heat the powder layer of the component material before, during and / or after the exposure by means of the radiation source in this area. Because of this heating by means of the heating device, hot cracking is reliably avoided, in particular when high-temperature alloys are used as the component material. Since the heating device is arranged on the coater, additional movement units for moving the heating device in the region of the assembly and joining zone of the component can initially be dispensed with. The heating device can be arranged so that it can not be moved on the coater, so that it is moved along or over the assembly and joining zone of the component platform by the movement of the coater. As a result, a simple structural design of the device is given in total. In addition, existing devices for the generative production of components can be retrofitted with a corresponding heating device which is arranged on the coater. This is then moved with the coater via a corresponding displacement unit of the coater on the assembly and joining zone of the component platform. By the terms "arranged" or "arrangement" is meant that the heating device can be directly or indirectly connected to the coater. For example, a mechanical connection with the coater is possible.
In weiteren vorteilhaften Ausgestaltungen der erfindungsgemäßen Vorrichtung ist die Heizvorrichtung derart ausgebildet ist, dass eine Erwärmung von zumindest der Pulverschicht des Bauteilwerkstoffs mittels induktiver Erwärmung und/oder elektromagnetischer Strahlung erfolgt. Dabei kann die Heizvorrichtung mindestens einen Laser und/oder mindestens eine Mikrowelle und/oder mindestens eine Infrarot-Strahlungsquelle und/oder mindestens eine UV- Strahlungsquelle umfassen. Des Weiteren kann die Heizvorrichtung mindestens eine Induktionsspule umfassen. Dabei wird unter Induktionsspule im Rahmen der vorliegenden Erfindung jede Vorrichtung verstanden, die eine induktive Erwärmung erzeugen kann, also beispielsweise unabhängig von der Anzahl der Windungen, so dass die Induktionsspule beispielsweise auch als In- duktions schleife bezeichnet werden kann. Dabei ist es möglich, dass die Vorrichtung mehrere an dem Beschichter angeordnete Induktionsspulen umfasst, die in einer oder mehreren Ebenen parallel zu einer Oberfläche der Aufbau- und Fügezone angeordnet sind. Insbesondere können zwei Induktionsspulen in zueinander gekreuzter Anordnung betrieben werden, wobei insbesondere im Kreuzungsbereich der Hochenergiestrahl der Strahlungsquelle zum Aufschmelzen und/oder Versintern des pulverförmigen Bauteilwerkstoffs vorgesehen sein kann. In einer weiteren vorteilhaften Ausgestaltung kann eine Induktionsspule nicht-verfahrbar an dem Beschichter und eine weitere Induktionsspule über eine Verfahreinheit am Beschichter verfahrbar angeordnet sein. Unter den Begriffen„angeordnet" oder„Anordnung" ist zu verstehen, dass die Verbindung zwischen den genannten Elementen direkt oder indirekt ausgebildet ist. In further advantageous embodiments of the device according to the invention, the heating device is designed such that a heating of at least the powder layer of the component material by means of inductive heating and / or electromagnetic radiation takes place. In this case, the heating device may comprise at least one laser and / or at least one microwave and / or at least one infrared radiation source and / or at least one UV radiation source. Furthermore, the heating device may comprise at least one induction coil. In the context of the present invention, induction coil means any device which can generate inductive heating, that is, for example, independently of the number of turns, so that the induction coil can also be referred to as an induction loop, for example. It is possible that the device comprises a plurality of arranged on the coater induction coils, which are arranged in one or more planes parallel to a surface of the building and joining zone. In particular, two Induction coils are operated in a mutually crossed arrangement, wherein in particular in the crossing region of the high energy beam of the radiation source for melting and / or sintering of the powdered component material can be provided. In a further advantageous embodiment, an induction coil can be arranged such that it can not be moved on the coater and a further induction coil can be moved on the coater via a displacement unit. By the terms "arranged" or "arrangement" is meant that the connection between said elements is formed directly or indirectly.
In weiteren vorteilhaften Ausgestaltungen der erfindungsgemäßen Vorrichtung ist die mindestens eine Heizvorrichtung an dem Beschichter verfahrbar angeordnet. Dabei kann der Beschichter mindestens eine Verfahreinheit umfassen, an der wiederum mindestens eine Heizvorrichtung angeordnet ist. Daher ergibt sich vorteilhafterweise die Möglichkeit, die Heizvorrichtung auch entgegen der Bewegungsrichtung des Beschichters zu verfahren, um so einen weiteren Bereich der Aufbau- und Fügezone einer Erwärmung durch die Heizvorrichtung unterziehen zu können. Ins- besondere ist es aber auch möglich, dass die Vorrichtung mindestens eine am Beschichter verfahrbar angeordnete Heizvorrichtung und mindestens eine am Beschichter nicht-verfahrbar angeordnete Heizvorrichtung umfasst. Durch die Anordnung von mindestens zwei Heizvorrichtungen an dem Beschichter kann wiederum vorteilhafterweise ein größerer Bereich der Aufbau- und Fügezone der Bauteilplattform und der in diesem Bereich aufgetragene Bauteilwerkstoff erwärmt werden. Unter den Begriffen„angeordnet" oder„Anordnung" ist zu verstehen, dass die Verbindung zwischen den genannten Elementen direkt oder indirekt ausgebildet ist. In further advantageous embodiments of the device according to the invention, the at least one heating device is arranged movably on the coater. In this case, the coater may comprise at least one moving part, on which in turn at least one heating device is arranged. Therefore, it is advantageously possible to move the heating device counter to the direction of movement of the coater so as to be able to subject a further region of the assembly and joining zone to heating by the heating device. In particular, however, it is also possible that the device comprises at least one heating device arranged movably on the coater and at least one heating device arranged non-movably on the coater. By arranging at least two heating devices on the coater, in turn advantageously a larger area of the assembly and joining zone of the component platform and the component material applied in this area can be heated. By the terms "arranged" or "arrangement" is meant that the connection between said elements is formed directly or indirectly.
Die relative Bewegbarkeit des Beschichters relativ zu der Bauteilplattform kann entweder durch die Bewegung des Beschichters mittels der entsprechenden Verfahreinheit oder durch Bewegen der Bauteilplattform erfolgen. Bei der letztgenannten Ausführungsform kann gegebenenfalls auf eine separate Verfahreinheit des Beschichters verzichtet werden. The relative mobility of the coater relative to the component platform can be accomplished either by the movement of the coater by means of the corresponding moving unit or by moving the component platform. In the latter embodiment, it may be possible to dispense with a separate displacement unit of the coater.
In einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung umfasst der Beschichter mindestens eine bewegbare Klinge, derart, dass die Klinge während einer Belichtung der Pulverschicht im Bereich der Aufbau- und Fügezone mittels des Hochenergiestrahl in den Beschichter zumindest teilweise rückziehbar ist. Unter dem Begriff„Klinge" sind dabei alle verwendbaren Glättvorrichtungen wie zum Beispiel Klingen, Rakel, Lippen, ein Kämme oder Walzen zu verstehen. Damit kann vorteilhafterweise gewährleistet werden, dass es zu keiner Beschädigung der Klinge durch den Hochenergiestrahl kommen kann, falls die Klinge derart an dem Beschichter angeordnet ist, dass diese zumindest teilweise während des Belichtungsvorgangs durch den Hochenergiestrahl in den Belichtungsbereich hineinragt. In a further advantageous embodiment of the device according to the invention, the coater comprises at least one movable blade, such that the blade is at least partially retractable during exposure of the powder layer in the region of the buildup and joining zone by means of the high energy beam into the coater. The term "blade" are all usable smoothing devices such as blades, squeegee, lips, a comb or Understand rolling. This can be advantageously ensured that there is no damage to the blade by the high energy beam, if the blade is arranged on the coater that this at least partially protrudes during the exposure process by the high energy beam in the exposure area.
In einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung umfasst die Vorrichtung mindestens eine Fokussiereinrichtung zur Fokussierung des Hochenergiestrahls. Dadurch ist gewährleistet, dass der Hochenergiestrahl unabhängig von einer möglichen Auf- oder Abbewegung der Bauteilplattform immer auf die zu verschmelzende und/oder zu versinternde Schicht des pulverförmigen Bauteilwerkstoffs fokussiert bleibt. In a further advantageous embodiment of the device according to the invention, the device comprises at least one focusing device for focusing the high-energy beam. This ensures that the high-energy beam, regardless of a possible up or down movement of the component platform, always remains focused on the layer of powdered component material to be fused and / or sintered.
In weiteren vorteilhaften Ausgestaltungen der erfindungsgemäßen Vorrichtung ist der Hochenergiestrahl ein Laser- oder Elektronenstrahl. In further advantageous embodiments of the device according to the invention, the high-energy beam is a laser or electron beam.
Ein zweiter Aspekt der Erfindung betrifft ein Verfahren zur Herstellung zumindest eines Bauteilbereichs eines Bauteils, insbesondere eines Bauteils einer Strömungsmaschine. Das Verfahren umfasst dabei zumindest folgende Schritte: a) Schichtweises Auftragen von mindestens einem pulverförmigen Bauteilwerkstoff mittels wenigstens einem Beschichter auf mindestens eine Bauteilplattform im Bereich einer Aufbau- und Fügezone, wobei der Beschichter relativ zu der Bauteilplattform bewegbar ist; A second aspect of the invention relates to a method for producing at least one component region of a component, in particular of a component of a turbomachine. The method comprises at least the following steps: a) layer-wise application of at least one powdered component material by means of at least one coater on at least one component platform in the region of a buildup and joining zone, wherein the coater is movable relative to the component platform;
b) Schichtweises und lokales Verschmelzen und/oder Versintern des Bauteilwerkstoffs durch Zuführen von Energie mittels wenigstens eines Hochenergiestrahls im Bereich der Aufbau- und Fügezone zum Ausbilden einer Bauteilschicht, wobei vor und/oder während und/oder nach dem schichtweisen und lokalen Verschmelzen und/oder Versintern des Bauteilwerkstoffs eine Erwärmung zumindest des im Bereich der Aufbau- und Fügezone angeordneten Bauteilwerkstoffs mittels mindestens einer Heizvorrichtung erfolgt;  b) layered and local fusion and / or sintering of the component material by supplying energy by means of at least one high energy beam in the region of the assembly and joining zone to form a component layer, wherein before and / or during and / or after the layered and local fusing and / or By sintering the component material, at least the component material arranged in the region of the assembly and joining zone is heated by means of at least one heating device;
c) Schichtweises Absenken der Bauteilplattform um eine vordefinierte Schichtdicke; und d) Wiederholen der Schritte a) bis c) bis zur Fertigstellung des Bauteilbereichs. Dabei ist die mindestens eine Heizvorrichtung an dem Beschichter angeordnet und während des Zuführens von Energie mittels des Hochenergiestrahls im Bereich der Aufbau- und Fügezone wird mindestens eine an dem Beschichter angeordnete Klinge von einer Oberfläche des Bauteilwerkstoffs wegbewegt. Durch die Anordnung der mindestens einen Heizvorrichtung an dem Be- schichter ist wiederum eine konstruktiv einfache Lösung zur Bewegung der Heizvorrichtung im Bereich der Aufbau- und Fügezone gewährleistet. Unter den Begriffen„angeordnet" oder„Anordnung" ist zu verstehen, dass die Heizvorrichtung direkt oder indirekt mit dem Beschichter verbunden werden kann. Beispielsweise ist eine mechanische Verbindung mit dem Beschichter möglich. Zudem ist gewährleistet, dass durch das Wegbewegen des Beschichters bzw. einer an dem Beschichter angeordneten Klinge von der Oberfläche des Bauteilwerkstoffs während der Belichtung mittels des Hochenergiestrahls eine Beschädigung des Beschichters oder der daran angeordneten Klinge vermieden wird. Dabei kann die Kline bewegbar ausgebildet sein, derart, dass die Klinge während einer Belichtung der Pulverschicht im Bereich der Aufbau- und Fügezone mittels des Hochenergiestrahls in dem Beschichter zumindest teilweise rückziehbar ist. Es ist aber auch möglich, dass zur Wegbewegung der Klinge von der Oberfläche des Bauteilwerkstoffs ein Absenken der Bauteilplattform erfolgt. Während des Absenkens der Bauteilplattform erfolgt vorteilhafterweise eine Veränderung der Positionierung eines Strahlfokus des Hochenergiestrahls relativ zur Oberfläche des Bauteilwerkstoffs. Es kann beispielsweise eine Fokussierung des Hochenergiestrahls auf die Oberfläche des Bauteilwerkstoffs erfolgen. Dadurch ist ein optimales Verschmelzen und/oder Versintern des Bauteilwerkstoffs in diesem Bereich gegeben. c) layer-wise lowering of the component platform by a predefined layer thickness; and d) repeating steps a) to c) until completion of the component area. In this case, the at least one heating device is arranged on the coater, and during the supply of energy by means of the high-energy beam in the region of the buildup and joining zone, at least one blade arranged on the coater is moved away from a surface of the component material. As a result of the arrangement of the at least one heating device on the coater, a structurally simple solution for moving the heating device in the region of the assembly and joining zone is again ensured. By the terms "arranged" or "arrangement" is meant that the heating device can be directly or indirectly connected to the coater. For example, a mechanical connection with the coater is possible. In addition, it is ensured that the moving away of the coater or a blade arranged on the coater from the surface of the component material during the exposure by means of the high-energy beam avoids damage to the coater or the blade arranged thereon. In this case, the Kline can be designed to be movable, such that the blade is at least partially retractable during exposure of the powder layer in the region of the assembly and joining zone by means of the high energy beam in the coater. But it is also possible that the movement of the blade from the surface of the component material, a lowering of the component platform takes place. During the lowering of the component platform advantageously takes place a change in the positioning of a beam focus of the high energy beam relative to the surface of the component material. For example, a focusing of the high-energy beam onto the surface of the component material can take place. This ensures optimal fusion and / or sintering of the component material in this area.
Ein dritter Aspekt der Erfindung betrifft einen Beschichter zur Verwendung in einer Vorrichtung zur generativen Herstellung zumindest eines Bauteilbereichs eines Bauteils. Erfindungsgemäß ist der Beschichter relativ zu einer Bauteilplattform der Vorrichtung bewegbar und zur Anordnung von mindestens einer Heizvorrichtung ausgebildet. Der erfindungsgemäße Beschichter ermöglicht es, dass eine Pulverschicht eines Bauteilwerkstoffs vor, während und/oder nach der Belichtung mittels einer Strahlungsquelle der Vorrichtung in diesem Bereich erwärmt wird. Aufgrund dieser Erwärmung mittels der Heizvorrichtung werden zuverlässig, insbesondere bei der Verwendung von Hochtemperaturlegierungen als Bauteil Werkstoff, Heißrissbildungen vermieden. Da die Heizvorrichtung an dem Beschichter angeordnet ist, kann zunächst auf zusätzliche Verfahreinheiten zur Bewegung der Heizvorrichtung im Bereich der Aufbau- und Fügezone des Bauteils verzichtet werden. Unter den Begriffen„angeordnet" oder„Anordnung" ist zu verstehen, dass der Beschichter direkt oder indirekt mit der Heizvorrichtung verbunden werden kann. Beispielsweise ist eine mechanische Verbindung mit der Heizvorrichtung möglich. A third aspect of the invention relates to a coater for use in a device for the generative production of at least one component region of a component. According to the invention, the coater is movable relative to a component platform of the device and designed for the arrangement of at least one heating device. The coater according to the invention makes it possible for a powder layer of a component material to be heated in this area before, during and / or after the exposure by means of a radiation source of the device. Due to this heating by means of the heating device, hot cracking is reliably avoided, in particular when using high-temperature alloys as a component material.

Weitere Merkmale der Erfindung ergeben sich aus den Ansprüchen, den Ausführungsbeispielen sowie anhand der Zeichnungen. Die vorstehend in der Beschreibung genannten Merkmale und Merkmalskombinationen sowie die nachfolgend in den Ausführungsbeispielen genannten Merkmale und Merkmalskombinationen sind nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen verwendbar, ohne den Rahmen der Erfindung zu verlassen. Dabei zeigt: Further features of the invention will become apparent from the claims, the exemplary embodiments and with reference to the drawings. The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the exemplary embodiments can be used not only in the particular combination specified, but also in other combinations, without departing from the scope of the invention.

Fig. 4 eine schematische Schnittdarstellung der Vorrichtung gemäß Figur 3. 4 is a schematic sectional view of the device according to FIG. 3.
Fig. 1 zeigt eine schematisch dargestellte Aufsicht auf eine erfindungsgemäße Vorrichtung 10 zur generativen Herstellung zumindest eines Bauteilbereichs eines Bauteils 12, insbesondere eines Bauteils 12 einer Strömungsmaschine. Insbesondere kann es sich dabei um ein Bauteil einer Turbine oder eines Verdichters eines Flugtriebwerks handeln. Die Vorrichtung 10 weist zudem einen Beschichter 14 zum Auftrag von mindestens einer Pulverschicht eines Bauteilwerkstoffs (nicht dargestellt) auf zumindest eine Aufbau- und Fügezone 20 einer absenkbaren Bauteilplattform 16 auf. Man erkennt, dass der Beschichter 14 mittels einer Verfahreinheit 30, welche mit einem Maschinengestell 32 der Vorrichtung 10 verbunden ist, bewegt werden kann. Die Bewegung des Beschichters 14 erfolgt dabei über und entlang der Bauteilplattform 16, so dass ein gleichmäßiger und schichtweiser Auftrag des pulverförmigen Bauteilwerkstoffs auf die Bauteilplattform 16 möglich ist. 1 shows a schematic plan view of an apparatus 10 according to the invention for the generative production of at least one component region of a component 12, in particular of a component 12 of a turbomachine. In particular, it may be a component of a turbine or a compressor of an aircraft engine. The device 10 also has a coater 14 for applying at least one powder layer of a component material (not shown) to at least one assembly and joining zone 20 of a lowerable component platform 16. It can be seen that the coater 14 can be moved by means of a moving unit 30, which is connected to a machine frame 32 of the device 10. The movement of the coater 14 takes place via and along the component platform 16, so that a uniform and layered order of the powdered component material on the component platform 16 is possible.
Des Weiteren erkennt man, dass an der Verfahreinheit 30 des Beschichters 14 eine erste Indukti- onsspule 24 angeordnet ist. Ungefährt senkrecht zu der ersten Induktionsspule 24 ist eine zweite Induktionsspule 28 an einer Verfahreinheit 26 angeordnet. Die Verfahreinheit 26 ist wiederum am Beschichter 14 angeordnet, so dass die zweite Induktionsspule 28 entlang einer Längserstreckung des Beschichters 14 bewegt werden kann. In dem dargestellten Ausführungsbeispiel sind die beiden Induktionsspulen in zueinander gekreuzter Anordnung ausgebildet. Man erkennt, dass durch eine derartige Anordnung der gesamte Bereich der Bauteilplattform 16 mittels der Induktionsspulen 24, 28 überdeckt und somit erwärmt werden kann. Des Weiteren wird deutlich, dass ein Hochenergiestrahl 22, insbesondere ein Laser- oder Elektronenstrahl, zwischen den Induktionsspulen 24, 28 hindurch auf die Pulverschicht des Bauteilwerkstoffs im Bereich einer Aufbau- und Fügezone 20 gerichtet werden kann. Insbesondere wird der Hochenergiestrahl 22 derart aus- gerichtet, dass er zwischen einen Kreuzungsbereich der Induktionsspulen 24, 28 hindurch dringen kann. In Fig. 1 sind zudem durch den punktförmigen Hochenergiestrahl 22 gebildeten Strahlspuren 34, insbesondere Laserspuren, dargestellt. Im Bereich der Strahlspuren 34 hat bereits ein Verschmelzen und/oder Versintern des Bauteilwerkstoffs stattgefunden. Man erkennt zudem, dass durch die Anordnung der Induktionsspulen 24, 28 an den Beschichter 14 diese für die Beschichtung nicht mehr aus dem Arbeitsbereich des Beschichters 14 entfernt werden müssen. Durch die Erwärmung der Pulverschicht mittels der Induktionsspulen 24, 28 im Bereich der Aufbau- und Fügezone 20 ist es möglich, vor, während und nach den Aufschmelzen des Bauteilwerkstoffs mittels des Hochenergiestrahls 22 und mit Fortschreiten der Erstarrungs- front einerseits gleichbleibende Induktionsbedingungen zu erzielen, sodass gleichbleibendeFurthermore, it can be seen that a first induction coil 24 is arranged on the displacement unit 30 of the coater 14. Approximately perpendicular to the first induction coil 24, a second induction coil 28 is disposed on a track 26. The traversing unit 26 is in turn arranged on the coater 14, so that the second induction coil 28 can be moved along a longitudinal extent of the coater 14. In the illustrated embodiment, the two induction coils are formed in a crossed arrangement. It can be seen that the entire area of the component platform 16 can be covered by means of the induction coils 24, 28 and thus heated by such an arrangement. Furthermore, it becomes clear that a high-energy beam 22, in particular a laser or electron beam, can be directed between the induction coils 24, 28 onto the powder layer of the component material in the region of a buildup and joining zone 20. In particular, the high-energy beam 22 is aligned in such a way that it can penetrate between an intersection region of the induction coils 24, 28. In Fig. 1 also formed by the point-shaped high-energy beam 22 beam traces 34, in particular laser tracks, are shown. In the area of the beam traces 34, a fusion and / or sintering of the component material has already taken place. It can also be seen that, due to the arrangement of the induction coils 24, 28 on the coater 14, they no longer have to be removed from the working area of the coater 14 for the coating. By heating the powder layer by means of the induction coils 24, 28 in the region of the assembly and joining zone 20, it is possible to achieve constant induction conditions before, during and after the melting of the component material by means of the high-energy beam 22 and with the progress of the solidification front consistent
Schmelzbedingungen mit definierten, lokalen Temperaturgradienten bei hohen Produktionsgeschwindigkeiten einstellbar sind. Andererseits wird gleichzeitig die Ausbildung von Rissen und dergleichen beim Erstarren vermieden. Fig. 2 zeigt eine schematische Schnittdarstellung der Vorrichtung 10 gemäß der Linie A-A inMelting conditions are adjustable with defined, local temperature gradients at high production speeds. On the other hand, the formation of cracks and the like during solidification is avoided at the same time. Fig. 2 shows a schematic sectional view of the device 10 according to the line A-A in
Fig. 1. Man erkennt, dass die mittels der Verfahreinheit 26 am Beschichter 14 angeordnete zweite Induktionsspule 28 in einer Ebene über der ersten, an der Verfahreinheit 30 des Beschichters 14 angeordneten ersten Induktionsspule 24 relativ zur der Bauteilplattform 16 angeordnet ist. Zudem erkennt man, dass der Beschichter 14 eine Klinge 18 für den schichtweisen Auftrag des pulverförmigen Bauteilwerkstoffs (nicht dargestellt) auf der Bauteilplattform 16 aufweist. Die Klinge 18 ist dabei bewegbar ausgebildet, derart, dass sie während einer Belichtung der Pulver- schicht im Bereich der Aufbau- und Fügezone 20 mittels des Hochenergiestrahls 22 in den Beschichter 14 zumindest teilweise rückziehbar ist. Alternativ zu der Klinge 18 können auch andere Glättvorrichtungen wie zum Beispiel Rakel, Lippen, ein Kämme oder Walzen verwendet werden.
