Abstract

A new technique is described for producing a metal matrix composite body whose reinforcement phase is formed in situ. Specifically, an infiltration enhancer material is applied to a surface of a substantially non-reactive material, e.g., a mold surface. A molten matrix metal is then contacted to the infiltration enhancer material. The molten matrix metal spontaneously infiltrates the infiltration enhancer material. Concurrent with infiltration, at least a portion of the infiltration enhancer material is reduced chemically by the matrix metal to form as a reaction product a ceramic material. The ceramic material, embedded by matrix metal, essentially constitutes a metal matrix composite (MMC) material. Upon formation of the MMC material having the reinforcement phase produced in situ, the process may be repeated by coating or depositing fresh infiltration enhancer material on the previously formed MMC material. In a particularly preferred embodiment, the matrix metal is forced to infiltrate against the force of gravity, the infiltration enhancer is applied by a chemical vapor deposition technique, and the surface against which the MMC is formed is readily separated intact from the MMC body upon completion of spontaneous infiltration and solidification of the matrix metal, thereby permitting the surface, e.g., a mold, to be reused in another MMC fabrication run.
