Abstract: New and improved automobile and light truck components are disclosed. Specifically, certain components traditionnally made from steel, sometimes hardened steel, such as cylinder liners, various valve train components, clutch discs, brake rotors and brake caliper pistons can now be made from aluminum based materials, thereby saving considerable weight. An aluminum/aluminum nitride metal matrix composite material is provided on the contacting or wear surfaces to provide adequate abrasion resistance, yet protect the engaging component from being excessively worn. The metal matrix composite layer can be applied to an aluminum based metal matrix composite substrate or to an unreinforced aluminum substrate. The A1/A1N surface is also easier to machine than most metal matrix composite materials.

Abstract: This invention relates to metal and metal matrix composite materials that are useful as, for example, brake rotors, clutch plates and other similar uses which benefit from material properties of the invention. In the case of metal matrix composite materials, clutch plates and brake rotors made according to the invention comprise an interconnected matrix metal embedding at least one filler material. For example, the at least one filler material comprises numerous acceptable filler materials present in a sufficient quantity to provide desired performance. The brake rotors and clutch plates according to the invention further comprise a coating on the surface thereof causing the metal or metal matrix composite body to function as a substrate. The coatings may be applied by various conventional techniques. Desirable results of placing a coating on a metal or metal matrix composite substrate brake rotor or clutch plate include a significant increase in the maximum operating temperature of the brake rotor or clutch plate and/or a significant reduction in weight in comparison to conventional materials, etc.
