Particulate reinforced metal matrix composites (PMMCs), possessing high wear resistance, are promising candidates for applications in wear and friction. This paper evaluates the research works on the tribological behaviors of PMMCs and discusses the effects of material factors and extrinsic conditions on the wear resistance, friction coefficient and wear loss of the counterpart. Three principal wear mechanisms for PMMSs are discussed. Potential approaches for designing high wear resistance PMMCs are also suggested.
