Tribological behaviour of aluminium alloy AA6061T6 reinforced with silicon carbide and alumina oxide particles (15% weight percentage of SiC, Al2O3 and Gr particles) fabricated by stir casting process was investigated. The wear and frictional properties of the metal matrix composites was studied by performing dry sliding wear test using a computerized pin-on-disc wear tester. Experiments were conducted based on the plan of experiments generated through Taguchi's technique. A L9 Orthogonal array was selected for analysis of the data. Investigation is to find the influence of applied load, sliding speed and sliding distance on wear rate, as well as the coefficient of friction during wearing process was carried out using ANOVA and regression equations for each response were developed for 15% SiC, Al2O3 and Gr particles reinforced AA-6061 T6 MMC's. Objective of the model was chosen as “smaller the better” characteristics to analyse the dry sliding wear behaviour. Results show that sliding speed has the highest influence followed by applied load and sliding distance was found most affecting term the wear rate and coefficient of friction respectively.
