Verfahren zum Wiederherstellen von Flächen die durch hohen Kompressionskontakten beaufschlagt werden

摘要

A process for refurbishing a worn surface (14,16) of a shroud support component (10) of a turbomachine, as well as a shroud support component (10) refurbished with the process. The process generally entails removing a surface region of the worn surface (14,16) so as to define a repair surface on the component (10). A braze tape (22,24) formed from a slurry to comprise a braze material and a wear-resistant alloy is then applied to the repair surface, followed by a heat treatment to cause the braze tape (22,24) to diffusion bond to the repair surface so as to define a built-up surface. The built-up surface is then machined to define a wear-resistant coating on the component (10).
