Abstract
A solid material is bonded to a metal cast thereagainst by means of a metallurgical diffusion bond. The solid material is coated with a latent exoergic coating which coating reacts exothermically to produce intermetallic phases at the surface of the solid when the metal is cast thereagainst. The heat generated by the intermetallic-phase-formation reaction promotes the diffusion bond.
