The tribological behavior of Si/sub 3/N/sub 4/ in sliding contact with itself, nodular cast iron, 316 stainless steel, and Inconel 718 is examined. The role of the environment and of the tribological characteristics breakaway friction, kinetic friction, and wear are measured in vacuum and air. The tribological behavior is shown to be strongly influenced by interactions with metallic alloys, which can lead to metal transfer, high friction, and ceramic wear. Surface oxide and adsorbed films from an air environment can stabilize the metal surfaces and reduce friction and wear. 26 references.
