Patent ID: 7222422

Claim:
A process for refurbishing a worn surface of a component subject to high compression contact, the process comprising the steps of: removing a surface region of the worn surface so as to define a repair surface on the component; forming a braze tape from a slurry, the braze tape comprising a powder of a metallic cobalt-base wear-resistant alloy and a powder of a cobalt-base braze material having a lower melting temperature than the wear-resistant alloy, wherein the wear-resistant alloy consists of, by weight, about 27 to about 29% molybdenum, about 16.5 to about 17.5% chromium, about 3.0 to about 3.5% silicon, up to about 3% iron, up to about 3% nickel, with the balance cobalt, minor alloying elements, and incidental impurities; applying the braze tape to the repair surface; heat treating the braze tape and the repair surface to cause the braze tape to diffusion bond to the repair surface so as to define a built-up surface; aging the braze tape at a temperature of about 1090° C. to about 1150° C. for a duration of about one to about four hours; and then machining the built-up surface to remove a surface portion of the braze tape and define a wear-resistant coating on the component.
