Abstract
Durch ein additives Herstellungsverfahren kann ein entsprechend hergestellter Coupon (13) mit einer gewünschten Orientierung hergestellt werden, der genau ein Fehlvolumen einer zu reparierenden Komponente (1) ersetzt.By an additive manufacturing process, a correspondingly produced coupon (13) can be produced with a desired orientation, which replaces exactly one missing volume of a component (1) to be repaired.
Description
Die Erfindung betrifft die Reparatur von gerichtet erstarrten Bauteilen, bei denen ein Coupon verwendet wird, der mittels eines additiven Herstellungsverfahrens (additive manufacture AM) hergestellt wird. The invention relates to the repair of directionally solidified components using a coupon made by an additive manufacturing AM.
Hochleistungsturbinen weisen gerichtet erstarrte Bauteile wie Einkristalle oder kolumnar erstarrte Bauteile auf. High-performance turbines have directionally solidified components such as single crystals or columnar solidified components.
Auch diese können für den erneuten Einsatz repariert werden, wobei jedoch die reparierte Stelle dieselbe Eigenschaft aufweisen soll wie das Substrat. These can also be repaired for reuse, but the repaired site should have the same property as the substrate.
Es gibt Möglichkeiten, durch Auftragsschweißen eine gerichtete Struktur zu erzeugen, jedoch ist das bei der Herstellung mit hohen Wärmegradienten verbunden, was zu Problemen führen kann. There are ways to create a directional structure by build-up welding, but this involves high thermal gradients during manufacture, which can lead to problems.
Es ist daher Aufgabe der Erfindung ein Verfahren aufzuzeigen, das dieses Problem überwindet. It is therefore an object of the invention to provide a method which overcomes this problem.
Die Aufgabe wird gelöst durch ein Verfahren gemäß Anspruch 1. The object is achieved by a method according to
In den Unteransprüchen sind weitere vorteilhafte Maßnahmen aufgelistet, die beliebig miteinander kombiniert werden können um weitere Vorteile zu erzielen. In the dependent claims further advantageous measures are listed, which can be combined with each other in order to achieve further advantages.
Die Figuren und die Beschreibung stellen nur Ausführungsbeispiele der Erfindung dar. The figures and the description represent only embodiments of the invention.
Es zeigen: Show it:
Eine Wärmeableitung aus einem Schmelzbad beim AM erfolgt gerichtet, so dass ein Gradient in Aufbaurichtung entsteht, was dazu führt, dass eine stängelförmige Kornstruktur bevorzugt entsteht. Beim schichtweisen Aufbau der Struktur bei der Herstellung des Coupons wird jeweils mindestens die vorhergehende Lage mit angeschmolzen. Somit wird beim Erstarrungsprozess von der vorherigen Lage die kristallographische Orientierung übernommen. A heat dissipation from a molten bath at the AM is directed, so that a gradient arises in the construction direction, which leads to a stem-shaped grain structure preferably arises. When layered structure of the structure in the production of the coupon at least the previous layer is also melted with. Thus, during the solidification process, the crystallographic orientation is adopted from the previous position.
Zuerst wird der defekte Bereich entfernt. First, the defective area is removed.
Als vorbereitender Schritt für die Herstellung des Coupons wird die kristallographische Orientierung – primär und sekundär – des zu reparierenden SX-Bauteils im Bereich der Oberfläche bestimmt. As a preparatory step for the production of the coupon, the crystallographic orientation - primarily and secondarily - of the SX component to be repaired in the area of the surface is determined.
Die Geometrie des fehlenden Volumens wird insbesondere über 3D-Laserscan bestimmt. Sie dient als Grundlage, um das 3D-Volumenfile für den AM-Prozess herzustellen, was letztlich zu einem exakt passenden, individuell angepassten Coupon führt. The geometry of the missing volume is determined in particular via 3D laser scanning. It serves as the basis to create the 3D volume file for the AM process, ultimately leading to a perfectly fitting, customized coupon.
Der Coupon wird mittels Selective Laser Melting aufgebaut. Dabei wird im Coupon die für das zu reparierende Bauteil passende kristallographische Orientierung über einen Saatkristall auf der Bauplattform mit der passenden Orientierung vorgegeben. The coupon is set up using Selective Laser Melting. In the coupon, the crystallographic orientation suitable for the component to be repaired is set via a seed crystal on the construction platform with the appropriate orientation.
Alternativ kann die Orientierung einer dünnen Scheibe des Originalbauteils benutzt werden, die in das SLM-Pulverbett eingelegt wird. Die Scheibe wird dabei von einer nur wenige μm dicken Pulverschicht bedeckt. Beim Auftreffen des Laserstrahls schmilzt die Pulverschicht und ein kleiner Teil der Originalbauteilscheibe. So wird beim Erstarren die Orientierung des zu reparierenden Bauteils in den Reparaturcoupon eingebracht. Alternatively, the orientation of a thin slice of the original component can be used, which is inserted into the SLM powder bed. The disk is covered by a few microns thick powder layer. When the laser beam strikes, the powder layer melts and a small part of the original component disk melts. Thus, during solidification, the orientation of the component to be repaired is introduced into the repair coupon.
Der entstandene Coupon mit der passenden Geometrie und kristallographischen Orientierung wird über ein Fügeverfahren eingefügt, vorzugsweise eine Hochtemperaturlötung mit borhaltiger Folie. The resulting coupon with the appropriate geometry and crystallographic orientation is inserted via a joining process, preferably a high-temperature soldering with boron-containing film.
