Take electrolytic copper powder and SiC powder as the raw materials, apply powder injection moulding to prepare SiCp/Cu composite, while the test result shows that only Cu and SiC exist in the sintered composite, the SiC particles evenly distribute within the Cu substrate. The friction coefficient and the morphology and elemental composition of the worn composite surface are measured in the fiction and wear test. The result shows that the friction coefficient of composite increase in a more gentle pace with the prolonging of the sliding time; the adhesion and plastic deformation of the worn surface of the composite containing 10 vol.% SiCp is light, and there exists certain abrasive wear; while the worn surface of the composite containing 15 vol.% SiCp show obvious abrasive wear, and there exist dense mechanically mixed layer; in addition to the inherent elements of the composite of Cu, Si and C, the worn surface also contains the elements of Fe and O.
