Friction Behaviors of SiC Particle-Reinforced Cu Matrix Composites

Abstract:

Article Preview

SiC particle reinforced Cu composite was fabricated by powder metallurgy and hot extrusion process. The friction behaviour of pure Cu, braze and composites was studied on a block-on-ring test. The blocks were slid against 40Cr steel rings under the lubrication of 232# machinery oil. It shows that the wear rate of pure Cu is about then times of the 5 vol.% Cu composite at a normal load of 300 N. The satisfied wear resistance prove the SiC is a promising reinforcement material for Cu matrix composite. However, the 20 vol.% SiC did not exhibit prospected wear resistance. The discussion of this phenomenon was conducted.
