Study on preparation of copper matrix composites reinforced by SiC and Graphite particles

The copper matrix composites reinforced by SiC and Graphite particle were fabricated by powder metallurgy. The density of the composite was tested by Archimedes theory, and the hardness were tested by FEM-700-type meter, and friction and wear properties of materials was tested by MG-2000 high-speed high temperature friction and wear tester. The results show that the copper matrix composites reinforced by SiC and Graphite particles are successfully fabricated by powder metallurgy, and the particle distribution is uniform, the hardness of composite materials decrease with the increasing of graphite content, and the hardness of composite materials increase with increasing of SiC content, the wear resistance of composite materials increases with the graphite content increase. This study not only extends theoretical scope of the study of the particle reinforced copper matrix composite, but also on application of practical significance of the copper matrix composites instead of copper and copper alloy.
