Abstract
Corrosion resistant metal, either platinum or MCrAlY is bonded to a corrosion sensitive metal such as nickel based superalloys by coating the surface with the corrosion resistant metal particles held in a binder and covering this with a metalide generating tape. This is then heated to cause the formation of the metalide coating on the metal surface, which in turn, bonds the corrosion resistant metal to the surface.
