Abstract: The Al6061-SiC MMC was prepared by stir casting method with 4% of MoS2, Cu, and C separately. Experiments were performed by using Taguchi's L9 orthogonal array on a pin-on-disc set-up to study the friction and wear behaviour of the composite materials. The effects of speed, pressure, and time on the friction and wear rate were studied. Analysis of variance and ranking of parameters were done using Minitab statistical analysis software. The friction coefficient of composites against EN-31 disc was found to be in the range of 0.22 to 0.36. Minimum and maximum wear rate is observed when Al6061-20SiC is reinforced with 4% MoS2 and 4% Gr respectively. The surface characteristics were analysed using SEM. The composite materials finds potential to be used as a light weight material in various sliding contact conditions. Further investigation on heat dissipation characteristics with addition of MoS2/Cu/C is recommended.
