Si3N4 reinforced Al6061 composite is fabricated by liquid metallurgy technique. Si3N4 particles are nickel coated prior to addition to molten metal to improve its wettability and to ensure excellent bond between matrix and the reinforcement. Metallographic studies, friction and wear tests were carried out using pin on disc type machine. Coefficient of friction and wear rate were measured at loads varying from 20–100N and sliding velocities from 0.314–1.574m/s. It is observed that Al6061-4wt%Si3N4 composites exhibited lower wear rate and lower coefficient of friction when compared with matrix alloy under all the test conditions studied.
