摘要
A brazing material for brazing tungsten/carbide/cobalt substrates (e.g., wear pads) to substrates comprising titanium or alloys thereof (e.g., fan or compressor blades). The brazing material includes gold, nickel, copper, and titanium present in respective amounts to provide a post-braze hardness of between 450 and 600 KHN to thereby increase the impact resistance of the braze joint. The substrates may be brazed by induction heating at temperatures less than about 1800° F. (982° C.).
