METHOD FOR ASSEMBLING PARTS MADE OF MATERIALS BASED ON SIC BY NON-REACTIVE REFRACTORY BRAZING, BRAZING COMPOSITION, AND JOINT AND ASSEMBLY OBTAINED BY SAID METHOD

摘要

The invention concerns a method for assembling at least two parts made of materials based on silicon carbide by non-reactive refractory brazing, which consists in contacting said parts with a non-reactive brazing composition and heating the assembly formed by the parts and the brazing composition at a brazing temperature sufficient to cause the brazing composition to melt so as to form a refractory joint. Said non-reactive brazing composition consists, in atomic percentages, of 40 to 97 % of silicon and 60 to 3 % of another element selected among chromium, rhenium, vanadium, ruthenium, iridium, rhodium, palladium, cobalt, platinum, cerium and zirconium and, prior to brazing, a SiC and/or C reinforcement is added to the composition. The invention also concerns a brazing composition for refractory brazing, the refractory joint and assemblies obtained by said method.
