In this study, A356.0 alloys were reinforced with varied percentage of Graphite by liquid metallurgy route and tested for microstructure, mechanical properties. Wear tests were conducted using Pin-on-Disc apparatus at a constant sliding velocity of 1m/s and load of 30N. Microstructure revealed uniform distribution of reinforcement in the matrix resulting in improved mechanical properties and wear resistance compared to un-reinforced material. The ceramic reinforced alloys were found to have improvement in mechanical properties and wear resistance which may be attributed to the improved bonding of reinforcement in the matrix.
