METHOD FOR REPAIRING SURFACE DAMAGE TO A TURBOMACHINE COMPONENT

摘要

A method for repairing surface damage to a turbomachine component that has a base material which has titanium with the base material having TiAl6V4 and/or pure titanium is provided. The method includes the following steps: mixing a solder that has a titanium-containing alloy and a powder which is distributed in the solder and which has the base material; applying the solder onto turbomachine component areas where the surface damage is located; introducing a quantity of heat into the solder and into the turbomachine component such that the alloy liquefies and the areas are thus wetted; and cooling the solder such that the alloy solidifies.

1. A method for repairing surface damage to a turbomachine component having a titanium-comprising base material, wherein the base material comprises TiAl6V4 and/or pure titanium, the method comprising:
mixing a solder comprising a titanium-comprising alloy and a powder which is distributed in the solder and comprises the base material, wherein a composition of the alloy is selected such that a melting temperature of the alloy is lower than a beta transus temperature of the base material, and the solder is mixed in such a way that a mass ratio of the alloy to the powder is at least 3:7 and at most 7:3; applying the solder to points of the turbomachine component at which the surface damage is located; introducing a quantity of heat into the solder and into the turbomachine component, such that the alloy becomes liquid and as a result the points are wetted; cooling the solder, such that the alloy becomes solid.
