ABSTRACT:
The invention produces a light metal alloy composite having a nickel coated graphite or carbon with a nickel-containing intermetallic phase within a portion of a casting. A mold is provided to cast a light metal into a predetermined shape. A nickel coated carbon phase structure is placed into a portion of the mold. The light metal is cast into the mold around the carbon structure to wet an interface between the light metal and the nickel coated carbon structure. A nickel-containing intermetallic phase is formed in the light metal proximate the nickel coated carbon to provide increased wear resistance. The light metal is then solidified to form the metal matrix composite.
