Abstract

Ceramic-metal composites are used in the fabrication of components for engines, particularly internal combustion engines. The composites are formed by infiltrating a molten metal into a porous ceramic matrix and cooling the metal to form a composite. Numerous engine components can be fabricated using this technique including valves, valve seats, exhaust port liners, pistons and rocker arms.
