Abstract

See full text

A method for joining, assembling, at least two parts comprising silicon carbide-based materials is provided. The parts are contacted with a non-reactive brazing composition, the assembly having the parts and the brazing composition is heated to a brazing temperature sufficient to melt the brazing composition, and the parts and the brazing composition are cooled so that, after solidification of the brazing composition, a moderately refractory joint is formed. The brazing composition is a binary alloy consisting, in atomic percentages, of 60% to 66% silicon and 34% to 40% nickel. Prior to contacting the parts with the brazing composition, a reinforcement is added. A composition comprising the brazing composition and a reinforcement is provided. A brazing paste, suspension comprising a powder of the brazing composition, a reinforcement, and an organic liquid cement, binder, or an organic viscous gel is provided. A joint and assembly obtained by the foregoing method is provided.
