ABSTRACT:
Novel processes for fabricating metal matrix composites consisting of discontinuous reinforcing particles in a metal matrix are described. In one aspect, reinforcing particles are coated with a metal matrix material by means of chemical vapor deposition using a volatile metal-containing compound, followed by consolidation of the metal-coated particles. In another aspect, reinforcing particles are coated with a metal matrix material by means of electrochemical deposition of a metal, followed by consolidation of the metal-coated particles. In yet another aspect, reinforcing particles coated with a metal matrix material by one of the aforesaid methods are blended with metal or alloy particles not containing such reinforcement, then consolidated.
