Dry Sliding Wear Behaviour of Garnet Particles Reinforced Zinc-Aluminium Alloy Metal Matrix Composites
Keywords:metal matrix composites, wear, wear parameters, abrasion, delamination.
The present investigation aims to evaluate the wear behaviour of zinc-aluminium (ZA-27) alloy composites reinforced
with garnet particles. The liquid metallurgy technique was used to fabricate the composites. The reinforcement content
was varied from 0 % to 20 % by weight in steps of 5 %. A pin-on disc wear testing machine was used to evaluate the
wear loss of composites. The results reveal that the wear loss of composites was less than that of the zinc-aluminium
alloy, but increased with increase of reinforcement in load and sliding speed. It was found that the wear resistant will
increase with increase in garnet content. The observations have been explained using scanning electron microscopy
(SEM) analysis of the worn surfaces.
