In the present work, the AA4015 alloy/Si3N4 metal matrix composites were manufactured at 10% and 30% volume fractions of Si3N4. The pin-on-disc wear test was conducted with different combinations of reinforcement, sliding distance, normal load, sliding speed. Based on the experimental results empirical models were established. The wear resistance increases with increase in volume fraction of Si3N4 in AA4015 alloy matrix. Combined effect of adhesion and abrasions were predominant in the wear mechanisms of AA4015 alloy/Si3N4 metal matrix composites.
