Abstract
Metal matrix composite materials are formed from a reinforcing, submicron-particle material, such as SiC, which is not easily wettable by a matrix metal, such as Al, and therefore cannot be uniformly dispersed in the matrix because the particles agglomerate. A coating 12 of material, such as Si, easily wettable by the matrix metal, is placed on the surface of the particles 10 before mixing the reinforcing particles in the matrix metal.
