ABSTRACT: The present paper reveals the wear behaviour of Zinc - Aluminium alloy reinforced with SiC
particulate metal matrix composite. The composite is prepared using liquid metallurgy
technique. The unlubricated pin-on disc wear test is conducted to find the wear behaviour of
the ZA43 alloy based composite. The sliding wear test is conducted for different load, speed
and time. The result reveals that wear rates of composite is reduced as reinforcement
increases. For the same working conditions wear rate increases with increasing load and
with increasing speed. The tested samples are examined by taking micro structure photos and
analyzed for the type of wear. Dominating wear types observed are delamination and
abrasion.
