Description

In the present research Al 7075/Al2O3 particulate MMC was fabricated by Stir casting Process with bottom pouring technique. Composite containing 10 volume fractions of alumina (Al2O3) reinforcements are used. Conventional stir casting processes with metal moulds are used for castings. The microstructure indicates uniform distribution of Al2O3 reinforcements. The Mechanical properties like Hardness and Tensile Strength found to increases with the increases in reinforcement contents as compared to unreinforced alloy. Dry sliding wear test were carried as per ASTM G-99 standard and Wear characterizations are carried out by finding wear rate, wear coefficient, coefficient of friction bases on the pin on disc wear test.
