Effect of Processing Parameters, Particle Characteristics and Metallic Coating on Properties of SiCp Copper Alloy Matrix Composites

Abstract:

Article Preview

The powder metallurgy technique was adopted to prepare SiCp copper alloy matrix composites. The mechanical properties of the composites were measured to investigate the influence of processing parameters, SiC particle characteristics and metallic coating (copper) of the SiC particles. It was found that the mechanical properties of the composites prepared by pressing, sintering, re-pressing, and resintering are superior to those of composites prepared by the pressing and sintering route, and that sintering temperature was an important factor in controlling composite properties. Changes in hardness, theoretical density, ultimate tensile strength, and wear resistance of composites containing SiC of varying silicon carbide content were observed. In all cases, composites made from copper coated SiCp exhibited better properties than those from uncoated particles.
