Abstract: In order to make labyrinth seal lips on the periphery of a metal moving part of a turbomachine, a thick layer of refractory material that adheres to the metal is made prior to assembling the moving part, the refractory material advantageously comprising at least one metal selected for example from Fe, Co, and Ni, together with at least one ceramic selected for example from borides, nitrides, carbides, and refractory oxides. The labyrinth seal lips that are to be made are machined to their final dimensions in the deposited thick layer.

Abstract: The method of the invention enables a coating to be made on at least one face to be protected of a metal substrate and/or article in order to improve its performance in terms of resistance to wear by friction, in particular at high temperature. The method comprises 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 made of a binder and a metal powder of a superalloy; cutting said flexible sheet to the dimensions of said face to be protected of a metal substrate and/or article in order to constitute a preform; placing said preform on said face to be protected of a metal substrate and/or article; and raising the assembly to a temperature enabling a coating to be formed by establishing a bond between said preform and said face to be protected.
