Abstract

Pure aluminum matrix composites reinforced with SiC particles were fabricated by powder metallurgy, which involves hot pressing. Effects of particles volume on hardness and wear resistance of composites were investigated. Hardness of composites proportionally increased with increasing volume fraction of particles and 30%SiCp/Al composite has maximum hardness and its hardness is 2.7 times greater than that of pure aluminum. Increasing the volume fraction of reinforcements was remarkably efficient for wearing at low and middle sliding speed. Wear surface observation shows that adhesive and abrasive wear occurred at low and middle sliding speed, and melt and seizure wear took place at high sliding speed.
