Metal matrix composites are an attractive choice for aerospace and automotive
application because of their stiffness -to- weight ratio. Composites with
aluminum and magnesium matrices have been investigated extensively, while
less work has been carried out on copper matrix composites. In the present study
powder metallurgy technique was used to prepare specimens of copper and
copper alloy matrix (Cu-Sn- Pb-Zn) reinforced with SiC particulate. The effect
of sintering temperature and volume fraction of Sic, particles on densification
was investigated. Also, the effect of particle characteristic of Sic, reinforcement
on mechanical properties and wear behavior under varying contact pressure and
sliding speed by using pin -disc was carried out.
