Patent ID: 7261784

Claim:
A method of making a coating on at least one face to be protected of a metal substrate and/or metal article in order to improve its performance in terms of resistance to friction wear, in particular at high temperature, the method comprising the following steps: providing a flexible sheet derived from at least one plate obtained by the technique of casting a strip by silkscreen printing from a viscous material comprising a metallic brazing binder and a metal powder including a superalloy; cutting said flexible sheet to the dimensions of said face to be protected of said metal substrate and/or metal article in order to constitute a preform; placing said preform on said face to be protected of said metal substrate and/or metal article; and raising the assembly to a temperature higher than the melting temperature of the metallic brazing binder but lower than the melting temperature of said metal powder so as to form a coating by establishing a bond between said preform and said face to be protected of said metal substrate and/or metal article.
