PROCEDE D'ASSEMBLAGE DE PIECES EN MATERIAUX A BASE DE SIC PAR BRASAGE NON-REACTIF, COMPOSITIONS DE BRASURE, ET JOINT ET ASSEMBLAGE OBTENUS PAR CE PROCEDE.

摘要

A method for assembling at least two parts made of silicon carbide-based materials by non-reactive brazing is disclosed. The two parts are contacted with a non-reactive brazing composition. The assembly formed by the parts and the brazing composition is heated to a brazing temperature sufficient to melt the brazing composition. The parts and the brazing composition are cooled so that, after solidification of the brazing composition, a moderately refractory joint is formed. The non-reactive brazing composition is a binary alloy composed, in mass percentages, of about 46% to 99% silicon and 54% to 1% neodymium.
