Beschichtungen von Bauteilen, wie z.B. Bondschichten oder Wärmedämmschichten von hochtemperaturbelasteten Bauteilen, wie z.B. Gasturbinenbauteilen, werden oft mittels Plasmaspritzen beschichtet, wie es in der US-PS 3,839,618 oder US-PS 4,447,466 beschrieben ist.Coatings of components, e.g. Bond layers or Thermal insulation layers of components exposed to high temperatures, such as. Gas turbine components are often made using plasma spraying coated, as in U.S. Patent 3,839,618 or U.S. Patent 4,447,466.

Ein Sprühkompaktierungsverfahren ist aus der US-PS 4,418,124 bekannt, bei dem massive Körper hergestellt werden.A spray compacting method is known from US Pat. No. 4,418,124 known, in which massive bodies are made.

Sprühkompaktierungsverfahren, bei dem ein geschmolzenes Metall verdüst wird und in eine Form gespritzt wird um massive dichte Bauteile herzustellen, sind in dem Artikel "Microstructure and properties of spray cast Cu-Zr-alloys", Materials Science and Engineering A145(1991), Seite 243-255 von R.P. Singh beschrieben.Spray compacting process in which a molten metal is atomized and injected into a mold for massive Manufacturing dense components are described in the article "Microstructure and properties of spray cast Cu-Zr alloys ", materials Science and Engineering A145 (1991), pages 243-255 of R.P. Singh described.

Die Herstellungsbedingungen von massiven dichten Bauteilen mittels einem Sprühkompaktierungsverfahren sind in dem Artikel "Impingement Behavior of a Spray Cast Aluminum Alloy" in dem Proceedings Conference "Solidification 1993 in San Antonia, Texas, Februar 15-19, 1998 von D.P. M Matson" beschrieben. The manufacturing conditions of massive dense components by means of a spray compacting process are in the article "Impingement Behavior of a Spray Cast Aluminum Alloy" in the Proceedings Conference "Solidification 1993 in San Antonia, Texas, February 15-19, 1998 by D.P. M Matson ".

In der US-PS 6,444,331 ist beschrieben, dass eine poröse Bondschicht, die mittels Plasmaspritzen hergestellt wird, zur besseren Haftung dient.US Pat. No. 6,444,331 describes a porous Bond layer, which is produced by means of plasma spraying, for serves better liability.

Aufgabe der vorliegenden Erfindung ist es, auf vereinfachte Art und Weise Schichten mit verbesserter Haftung, insbesondere dicke Schichten, herstellen zu können.The object of the present invention is to simplify Way layers with improved adhesion, in particular to be able to produce thick layers.

Die Aufgabe wird gelöst durch die Verwendung einer Sprühkompaktierungsanlage gemäß Anspruch 1 und ein Schichtsystem gemäß Anspruch 2 und Anspruch 3.The task is solved by using a spray compacting system according to claim 1 and a layer system according to Claim 2 and Claim 3.

In den Unteransprüchen sind weitere vorteilhafte Ausgestaltungen des Schichtsystems beschrieben.Further advantageous refinements are in the subclaims of the layer system.

Es zeigen

  • Figur 1 vereinfacht eine Sprühkompaktierungsanlage zwecks Verwendung zur Erzeugung einer Beschichtung auf einem Bauteil,
  • Figur 2 ein erfindungsgemäßes Schichtsystem und
  • Figur 3 ein weiteres erfindungsgemäßes Schichtsystem.
    • Show it
  • FIG. 1 simplifies a spray compacting plant for the purpose of producing a coating on a component,
  • Figure 2 shows a layer system according to the invention and
  • Figure 3 shows another layer system according to the invention.

    • Figur 1 zeigt eine Sprühkompaktierungsanlage 1, die verwendet wird, um zumindest eine erfindungsgemäße Schicht 16 (Figur 2) auf einem Substrat 30 (Figur 2) zu erzeugen, wobei die Schicht 16, die auch eine Zwischenschicht 16 sein kann, auf dem Substrat 30 haften soll.Figure 1 shows a spray compacting plant 1 used to at least one layer 16 according to the invention (FIG. 2) to produce on a substrate 30 (Figure 2), the Layer 16, which can also be an intermediate layer 16 should adhere to the substrate 30.

    In der Sprühkompaktierungsanlage 1 wird beispielsweise aus einer Düse 4 aufgeschmolzenes, bspw. metallisches, Material ausgedüst, so dass ein Materialstrom aus zumindest teilweise flüssigen Teilchen 7 entsteht, die auf die Oberfläche 13 eines Bauteils 10 auftreffen und dort eine Schicht 16, 19 (Fig. 2, 3) erzeugen. In the spray compacting plant 1, for example a nozzle 4 melted, for example. Metallic, material sprayed out so that a flow of material at least partially liquid particles 7 are formed which on the surface 13 of a component 10 and there a layer 16, 19 (Fig. 2, 3) generate.

    Im Gegensatz zu den herkömmlichen Sprühkompaktierungsanlagen werden die geschmolzenen Teilchen 7 nicht in eine Form eingedüst, wo sie einen massiven Körper bilden sollen, sondern bilden eine Schicht 16 auf einem Bauteil 10.In contrast to conventional spray compacting systems the molten particles 7 are not injected into a mold, where they should form a massive body, but form a layer 16 on a component 10.

    Insbesondere können mit dieser Beschichtungsmethode einfach, kostengünstig und sehr schnell dicke Schichten auf einem Bauteil 10 hergestellt werden.In particular, with this coating method, inexpensive and very fast thick layers on a component 10 are manufactured.

    Die Mikrostruktur der Schicht kann durch die Verfahrensparameter der Sprühkompaktierungsanlage eingestellt werden. So können die Porosität und/oder Hinterschneidungen gezielt eingestellt werden.The microstructure of the layer can be determined by the process parameters the spray compacting system can be set. So can target the porosity and / or undercuts can be set.

    Figur 2 zeigt einen Querschnitt durch ein Schichtsystem 28 eines Bauteils 1, das in einer Sprühkompaktierungsanlage 1 hergestellt worden ist.FIG. 2 shows a cross section through a layer system 28 of a component 1, which in a spray compacting plant 1 has been manufactured.

    Auf dem Bauteil 1 ist eine Zwischenschicht 16 vorhanden, die mittels Sprühkompaktierung hergestellt worden ist.An intermediate layer 16 is present on the component 1 has been produced by spray compacting.

    Die Zwischenschicht 16 kann dicht sein aber auch durch entsprechende Variation der Verfahrensparameter eine poröse Struktur ggf. auch mit Hinterschneidungen 22 aufweisen, die eine bessere Verankerung einer auf der Schicht 16 aufgebrachten Schicht 19 gegenüber einer Schicht ohne Hinterschneidungen und/oder Poren ermöglichen.
    Die verbesserte Haftung wird nicht nur durch die Hinterschneidungen 22 erreicht, sondern auch durch die vergrößerte Kontaktfläche zwischen der Schicht 16 und 19.    The intermediate layer 16 can be dense but, by appropriate variation of the process parameters, can also have a porous structure, possibly with undercuts 22, which enable better anchoring of a layer 19 applied to the layer 16 compared to a layer without undercuts and / or pores.
    The improved adhesion is achieved not only by the undercuts 22, but also by the increased contact area between the layers 16 and 19.

    Solche Schichten 16 mit Hinterschneidungen 22 können auch mit anderen Methoden (Plasmaspritzen, CVD; PVD) hergestellt werden. Such layers 16 with undercuts 22 can also be used other methods (plasma spraying, CVD; PVD) become.

    Die Schicht 19 kann, muss aber nicht in einer Sprühkompaktierungsanlage 1 hergestellt worden sein.Layer 19 can, but does not have to, in a spray compacting plant 1 have been produced.

    Beispielsweise ist das Bauteil 10 eine Turbinenschaufel oder allgemein ein Bauteil 10, das hochtemperaturbelastet ist, und dessen Substrat 30 beispielsweise aus einer nickel- oder kobaltbasierten Superlegierung besteht.
    Die Schicht 16 ist eine so genannte Zwischenschicht der Zusammensetzung MCrAlY, wobei M für ein Element der Gruppe Eisen, Nickel oder Cobalt steht.
    Die Schicht 19 kann eine Verankerungsschicht oder keramische Wärmedämmschicht sein.    For example, the component 10 is a turbine blade or generally a component 10 that is exposed to high temperatures and whose substrate 30 consists, for example, of a nickel- or cobalt-based superalloy.
    Layer 16 is a so-called intermediate layer of the composition MCrAlY, where M stands for an element from the group iron, nickel or cobalt.
    Layer 19 can be an anchoring layer or ceramic thermal barrier coating.

    Figur 3 zeigt ein Schichtsystem 28, das nur eine Schicht 16 aufweist.
    Die Schicht 16 hat eine geringe Porosität und ist beispielsweise mindestens 0,5 mm dick.
    Solche dicken Schichten lassen sich besonders gut mittels in einer Sprühkompaktierungsanlage 1 herstellen.    FIG. 3 shows a layer system 28 which has only one layer 16.
    Layer 16 has a low porosity and is, for example, at least 0.5 mm thick.
    Such thick layers can be produced particularly well by means of a spray compacting system 1.
