Abstract : Composite materials consisting of copper metal-matrices with a solid lubricant phase of intercalated (NiCl2) graphite have been prepared and studied in sliding wear against type 440C stainless steel at normal temperatures in air. Results on the controlling wear and friction mechanisms in these materials are presented. Beneficial effects were found up to about 15 volume percent intercalated graphite. An analytical model has been developed that relates composite wear to mechanical and tribological properties of the different solid phases in the composite and the interface film.
