Fabrication of SiC_p/Cu Composites with SiC_w/SiC_(np) hybrid addition

摘要

SiC_p/Cu hybrid composites were fabricated by hot press sintering technology. Micron SiC particle (SiC_p), SiC wisker (SiC_w) and nano SiC particle (SiC_(np)) were chosen as hybrid reinforcement. The reinforcement distributed uniform in the substrate after electro-less plating. XRD, SEM and Vickers hardness apparatus were utilized to character phase constitution, surface morphology and hardness of SiC_p/Cu composites. The result showed that addition of nano-SiC_p improve Vickers' hardness and bending strength compared with SiC_w and SiC_(w+np) hybrid material.
