Among all metal matrix composites, A356 is the most applicable matrix due to its low density and exhibits nominal strength with soft nature. This proposed study is concerned with the examination of mechanical and tribological behavior of virgin A356 alloy and A356 reinforced with 10wt.% power plant waste flyash particles composites were processed by liquid metallurgy stir cum squeeze casting technique. The fabricated composites expose enhanced higher hardness when compared to the virgin A356 alloy due to the presence of flyash particles in the matrix. The wear and friction behavior of casted samples were evaluated with a pin on disk tribometer apparatus under dry and wet sliding environment at the presence of lubricant (SAE 80W-90) by varying sliding load of 10N-40N and sliding velocity of 1-3 m/s respectively. Wear rate increase with the increasing load and sliding velocity.
