Abstract

Die Erfindung betrifft ein Coupon, der als Substrat eine gesinterte Form aus zwei Pulvern aufweist, wobei das zweite Pulver ein gegenüber dem ersten Pulver eine um mindestens 10K niedrigere Schmelztemperatur aufweist, wobei auf dem gesinterten Substrat (4) eine Folie vorhanden ist, das gegenüber dem zweiten Pulver des Substrats (4) einen um mindestens 10K niedrigeren Schmelzpunkt aufweist. Ein erfindungsgemäßer Coupon weist zur besseren Fixierung eine weitere dünne Schicht aus einer Lotfolie auf, die mit der vorgesinterten Form durch Sintern verbunden ist.The invention relates to a coupon having as a substrate a sintered form of two powders, wherein the second powder has a melting temperature lower than the first powder by at least 10K, wherein on the sintered substrate (4) there is a film opposite to the one second powder of the substrate (4) has a melting point at least 10K lower. A coupon according to the invention has, for better fixing, a further thin layer of a solder foil, which is connected to the presintered form by sintering.

Description

Die Erfindung betrifft einen Coupon, der eine aufgesinterte Lotfolie aufweist, ein Verfahren und ein Bauteil. The invention relates to a coupon having a sintered solder foil, a method and a component.

Zur Reparatur von geschädigten Turbinenkomponenten kann eine strukturelle Reparatur durchgeführt werden, bei der die geschädigten Bereiche aus der Turbinenschaufel herausgetrennt werden und durch vorgefertigte Inserts aus dem gleichen Material ersetzt werden. Diese Inserts, „Coupons“ oder PSP, können mittels einer konventionellen Lotfolie in den abgetrennten Bereich eingefügt werden. Bei der Lotfolie besteht allerdings das Problem, dass diese in der Regel nur eine Dicke von 0,05–0,1mm aufweist. Sofern der Lötspalt, der sich zwischen der ausgemuldeten Komponente und dem Coupon ergibt, diese Dicke überschreitet, kommt es zu einer unvollständigen Anbindung des Coupons. Damit ist eine sehr präzise Vorbereitung der Komponente und des Coupons erforderlich, die mit hohen Kosten verbunden ist. To repair damaged turbine components, a structural repair may be performed in which the damaged areas are separated from the turbine blade and replaced with prefabricated inserts of the same material. These inserts, "coupons" or PSPs, can be inserted into the separated area using a conventional solder foil. The problem with the solder foil, however, is that it generally only has a thickness of 0.05-0.1 mm. If the solder gap, which results between the tolerated component and the coupon, exceeds this thickness, there is an incomplete connection of the coupon. This requires a very precise preparation of the component and the coupon, which is associated with high costs.

Eine Möglichkeit stellen flexible Tapes dar, die jedoch aufwendig zu applizieren sind. Weiterhin verfügen die flexiblen Tapes über einen Binderanteil, der das Risiko einer Porenbildung im Lötspalt birgt, sofern der Binder während des Lötens nicht ausgasen kann. One possibility is flexible tapes, which are expensive to apply. Furthermore, the flexible tapes have a binder content, which carries the risk of pore formation in the soldering gap, if the binder can not outgas during soldering.

Es ist daher Aufgabe der Erfindung, oben genanntes Problem zu lösen. It is therefore an object of the invention to solve the above-mentioned problem.

Die Aufgabe wird gelöst durch einen Coupon gemäß Anspruch 1, einem Verfahren gemäß Anspruch 5 und einem Bauteil gemäß Anspruch 8. The object is achieved by a coupon according to claim 1, a method according to claim 5 and a component according to claim 8.

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 wird vorgeschlagen, eine Lotfolie direkt auf Substrate von Coupons vorzugsweise aufzusintern. Bei den Folien könnte es sich um flexible Folien mit der gewünschten Lot-/ Grundwerkstoffmischung handeln. Diese könnten in der passenden Geometrie und Dicke hergestellt werden und bei niedrigen Temperaturen auf die Coupons aufgesintert werden. In diesem Schritt könnte der Binder ausgasen, so dass die Gefahr der Porenbildung deutlich reduziert werden kann. Es wäre auch denkbar, die Coupons vollständig applikationsfertig mitsamt dem aufgesinterten Tape zu beziehen, so dass im Rahmen der Applikation lediglich noch die Komponente vorbereitet werden müsste. It is proposed to preferably sinter a solder foil directly onto substrates of coupons. The films could be flexible films with the desired solder / base material mixture. These could be made in the proper geometry and thickness and sintered on the coupons at low temperatures. In this step, the binder could outgas, so that the risk of pore formation can be significantly reduced. It would also be conceivable to obtain the coupons completely ready for application together with the sintered-on tape, so that in the context of the application only the component would have to be prepared.

Dadurch kann die Wirtschaftlichkeit der Coupon-Repair deutlich erhöht werden. Die Coupon-Repair als innovative Reparaturtechnologie führt zu einer Erweiterung des Reparaturumfanges und einer Reduzierung der Anschlussrate. As a result, the cost-effectiveness of the coupon repair can be significantly increased. The coupon repair as an innovative repair technology leads to an extension of the scope of repair and a reduction of the connection rate.

1 zeigt einen erfindungsgemäßen Coupon 1. 1 shows a coupon according to the invention 1 ,

Der Coupon 1 weist ein Substrat 4 auf. The coupon 1 has a substrate 4 on.

Das Substrat 4 ist in bekannter Weise eine Mischung aus zumindest zwei verschiedenen Pulver, die zu einer Form gesintert werden. The substrate 4 is in a known manner a mixture of at least two different powders which are sintered into a mold.

Die zwei verschiedenen Pulver stellen vorzugsweise zum einen ein Material eines Grundwerkstoffs eines Bauteilsubstrats 10 (2) dar, das repariert werden soll als auch ein zweites Material, insbesondere Pulver, das gegenüber dem ersten Material eine um mindestens 10K niedrigere Schmelztemperatur aufweist. The two different powders preferably provide, on the one hand, a material of a base material of a component substrate 10 ( 2 ), which is to be repaired, as well as a second material, in particular powder, which has a melting point which is at least 10K lower than the first material.

Vorzugsweise sind das nickel- oder kobaltbasierte Superlegierungen, insbesondere gemäß 3 oder Modifikationen davon mit Schmelzpunkterniedrigern. Preferably, the nickel- or cobalt-based superalloys, in particular according to 3 or modifications thereof with melting point depressants.

Hierfür können bekannte flexible Lotfolien 7 verwendet werden. On the substrate 4 of the coupon 1 is a solder foil 7 present, whose layer thickness is significantly thinner, but in particular at least 50%, very particularly at least 70% made thinner than the substrate 4 of the coupon 1 , For this purpose, known flexible Lotfolien 7 be used.

Vorzugsweise sind das nickel- oder kobaltbasierte Superlegierungen, insbesondere gemäß 3 oder Modifikationen davon mit Schmelzpunkterniedrigern. Preferably, the nickel- or cobalt-based superalloys, in particular according to 3 or modifications thereof with melting point depressants.

The solder foil 7 again indicates the melting temperature Ts of the substrate 4 or the second material of the coupon 4 , in turn, at least 10K lower melting temperature.

Zur Herstellung wird ein bekanntes Substrat 4 eines Coupons 1 aus dem Stand der Technik verwendet, das mit einer Lotfolie 7 aus dem Stand der Technik in einem separaten Herstellungsgang durch Sintern miteinander verbunden wird.
