Description

Coupon mit aufgesinterter Lotfolie, Verfahren und Bauteil  Coupon with sintered solder foil, process and component
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 ge¬ schädigten Bereiche aus der Turbinenschaufel herausgetrennt werden und durch vorgefertigte Inserts aus dem gleichen Mate- rial ersetzt werden. Diese Inserts, „Coupons" oder PSP, kön¬ nen mittels einer konventionellen Lotfolie in den abgetrennten Bereich eingefügt werden. Bei der Lotfolie besteht aller¬ dings 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 Anbin- dung des Coupons. Damit ist eine sehr präzise Vorbereitung der Komponente und des Coupons erforderlich, die mit hohen Kosten verbunden ist. For the repair of damaged turbine components a structural repair can be performed, in which the ge ¬ damaged areas are separated out of the turbine blade and are replaced by preformed inserts of the same Mate rial. These inserts, "coupons" or PSP, Kings ¬ NEN be inserted into the separated area by means of a conventional solder foil In the solder foil consists of all ¬ recently the problem that they generally only have a thickness of 0.05 -. 0.1 mm comprising If the gap between the component and the coupon is more than that, the coupon will be incomplete, which means that the component and the coupon must be prepared very precisely and at a high cost ,
Eine Möglichkeit stellen flexible Tapes dar, die jedoch auf¬ wendig zu applizieren sind. Weiterhin verfügen die flexiblen Tapes über einen Binderanteil, der das Risiko einer Porenbil¬ dung im Lötspalt birgt, sofern der Binder während des Lötens nicht ausgasen kann. One way represent flexible tapes, however, are to apply to ¬ agile. Furthermore, the flexible tapes have a binder content, which carries a risk of Porenbil ¬ dung in the soldering gap, provided that the binder can not outgas during brazing.
Es ist daher Aufgabe der Erfindung, oben genanntes Problem zu lösen . Die Aufgabe wird gelöst durch einen Coupon gemäß Anspruch 1, einem Verfahren gemäß Anspruch 5 und einem Bauteil gemäß Anspruch 8. It is therefore an object of the invention to solve the above-mentioned problem. 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 kön¬ nen, um weitere Vorteile zu erzielen. Die Figuren und die Beschreibung stellen nur Ausführungsbeispiele der Erfindung dar. In the dependent claims further advantageous measures are listed, which are combined with each other Kings ¬ nen to obtain further advantages. 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 Temperatu¬ ren 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 müss- te . 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 appropriate geometry and thickness and are sintered at low tempera ¬ ren on the coupons. 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 Repara¬ turtechnologie führt zu einer Erweiterung des Reparaturumfan- ges 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 Repara ¬ turtechnologie leads to an expansion of Reparaturumfan- ges and a reduction in the connection rate.
Figur 1 zeigt einen erfindungsgemäßen Coupon 1. FIG. 1 shows a coupon 1 according to the invention.
Der Coupon 1 weist ein Substrat 4 auf. The coupon 1 has a substrate 4.
Das Substrat 4 ist in bekannter Weise eine Mischung aus zu¬ mindest zwei verschiedenen Pulver, die zu einer Form gesintert werden. Die zwei verschiedenen Pulver stellen vorzugsweise zum einen ein Material eines Grundwerkstoffs eines Bauteilsubstrats 10 (Figur 2) dar, das repariert werden soll als auch ein zweites Material, insbesondere Pulver, das gegenüber dem ersten Mate- rial eine um mindestens 10K niedrigere Schmelztemperatur auf¬ weist. The substrate 4 is in a known manner a mixture of at least two different ¬ powders which are sintered into a mold. The two different powders is preferably used for a material of a base material of a component substrate 10 (Figure 2) is to be repaired and a second material, in particular powder, which has a lower by at least 10K melting temperature ¬ compared to the first material ,
Vorzugsweise sind das nickel- oder kobaltbasierte Superlegie- rungen, insbesondere gemäß Figur 3 oder Modifikationen davon mit Schmelzpunkterniedrigern . Preferably, these are nickel- or cobalt-based superalloys, in particular according to FIG. 3, or modifications thereof with melting point depressants.
Auf dem Substrat 4 des Coupons 1 ist eine Lotfolie 7 vorhan¬ den, deren Schichtdicke deutlich dünner ist, insbesondere aber mindestens 50%, ganz insbesondere mindestens 70% dünner ausgeführt ist als das Substrat 4 des Coupons 1. Hierfür kön¬ nen bekannte flexible Lotfolien 7 verwendet werden. On the substrate 4 of the coupon 1, a solder foil is 7 EXISTING ¬, whose layer thickness is much thinner, but especially at least 50%, is carried out more in particular at least 70% thinner than the substrate 4 of the coupon 1. For this purpose, Kings ¬ NEN known flexible solder foils 7 are used.
Vorzugsweise sind das nickel- oder kobaltbasierte Superlegie- rungen, insbesondere gemäß Figur 3 oder Modifikationen davon mit Schmelzpunkterniedrigern. Preferably, these are nickel- or cobalt-based superalloys, in particular according to FIG. 3, or modifications thereof with melting point depressants.
Die Lotfolie 7 weist wiederum gegenüber der Schmelztemperatur Ts des Substrats 4 oder des zweiten Materials des Coupons 4, eine wiederum mindestens 10K niedrigere Schmelztemperatur auf. The solder foil 7 again has a melting temperature Ts of the substrate 4 or of the second material of the coupon 4, which in turn is 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. For the production, a known substrate 4 of a prior art coupon 1 is used, which is connected to a prior art solder foil 7 in a separate manufacturing process by sintering.
Ein solcher modifizierter Coupon 1 kann zur Reparatur eines Bauteilsubstrats 10 eines Bauteils 11 oder zur Neuherstellung verwendet werden (Fig. 2) . Such a modified coupon 1 can be used to repair a component substrate 10 of a component 11 or to make it new (FIG. 2).
Dabei kommt der Coupon 1 mit der Lotfolie 7 auf eine Auflage¬ fläche 13 des zu reparierenden Bauteilsubstrats 10 in Kontakt und wird erneut versintert, so dass ein repariertes Bauteil 11 oder ein Neubauteil aus mehreren Komponenten entsteht. In this case, the coupon 1 comes with the solder foil 7 on a support ¬ surface 13 of the component to be repaired substrate 10 in contact with and is sintered again so that a repaired component 11, or a new part of a plurality of components is produced.
