Abstract
A brazing assembly includes a tungsten/carbide/cobalt substrate (e.g., wear pad), a second substrate including titanium or titanium alloy (e.g., a midspan shroud of a fan or compressor blade) and a brazing material including gold, nickel, and copper present in respective amounts to improve the ductility of the braze joint. A brazed article includes a first substrate, a second substrate, and a braze joint having a post-braze hardness of between 450 and 600 KHN. A method to improve the impact resistance of a braze joint between a tungsten/carbide/cobalt substrate and a substrate including titanium or alloy thereof includes utilizing a brazing material including gold, nickel, and copper and brazing at temperatures less than about 1900° F. (1038° C.).
