Stir casting is an economical method to produce aluminum matrix composites (AMCs). In the present work, Aluminum alloy AA6061 reinforced with various amounts (0, 5, 10 and 15wt. %) of SiC particles were prepared. The matrix alloy was melted in a furnace and stirred to form a vortex. SiC particles were added to the periphery of the vortex and the composite melt was solidified in a permanent mold. The microstructures of the AMCs were studied using optical and scanning electron microscopy. SiC particles were observed to refine the grains and were distributed homogeneously in the aluminum matrix. SiC particle clusters were also seen in a few places. SiC particles were properly bonded to the aluminum matrix. Dry sliding wear behavior was analyzed by Pin on Disc apparatus. The reinforcement of SiC particles improved the wear resistance of the AMCs.The details of worn surface and wear debris are also presented in this paper.
