Method for coating parts made of material based on sic, coating compositions, and resulting coated parts
First Claim
1. A method for coating of a part made of silicon carbide material, wherein a coating compound is applied to at least one surface of said part and the assembly formed by the part and the coating compound is heated to a temperature sufficient to cause the surface of the coating compound to melt in order to coat said piece with a deposit of silicon carbide material, wherein the coating compound is a non-reactive composition comprised, in atomic percentages, of 40 to 97% silicon and 60 to 3% of another element selected from chrome, rhenium, titanium, vanadium, ruthenium, iridium, rhodium, palladium, cobalt, platinum, cerium and zirconium and, wherein prior to heating, a reinforcement of SiC and/or C is added.

Abstract
A method for covering a part made of silicon carbide material, wherein a coating compound is applied to at least one surface of said part and the assembly formed by the part and the coating compound is heated to a temperature sufficient to cause the surface of the coating compound to melt in order to coat said piece with a deposit of silicon carbide material and, wherein the coating compound is a non-reactive composition comprised of, in atomic percentages, from 40 to 97% silicon and 60 to 3% of another element selected from among chrome, rhenium, titanium, vanadium, ruthenium, iridium, rhodium, palladium, cobalt, platinum, cerium and zirconium and, wherein prior to heating, a SiC and/or C reinforcement is added.
