Method of assembly of pieces of materials based on sic by brazing of refractory not reactant, brazing solder composition, and seal and the assembly obtained by this refractory

摘要

Method of assembly of at least two parts made of materials based on silicon carbide by brazing material is not reactive, in which are placed in contact with these parts with a brazing solder composition is not reactive and heating the assembly formed by the parts and the brazing solder composition to a brazing temperature sufficient to melt the brazing solder composition in order to form a refractory joint, in which the brazing solder composition is not reactive is constituted, in atomic percentages, of 40 to 97% of silicon and 60 to 3% of another element chosen from among chromium, rhenium, titanium, vanadium, ruthenium, iridium, rhodium, palladium, cobalt, the plate, the cerium and zirconium and in which, before the brazing, the addition of a reinforcement of sic and / or c.composition brazing composition for the brazing refractory. Seal and refractory assembly obtained by the process.
