Abstract

In this study, hybrid surface composites were fabricated using friction stirring technique to improve the tribological properties of AA6082 aluminum alloy, which has various industrial applications. Micro-scale SiC and n-Al2O3 reinforcements were used in the hybrid composites produced. The rotational and travel speeds were chosen as chosen as 1250 rpm and 40 mm min(-1), respectively. After the double pass production, it was determined that the homogeneous particle distribution in the surface region lost this homogeneity in the lower regions of the surface. The hardness of the hybrid surface composites was found to be approximately 44.2% higher than AA6082 aluminum alloy. It was determined that the wear resistance of SiC/n-Al2O3 reinforced hybrid surface composites produced by friction stir processing was up to 68.5% higher than non-reinforced AA6082 alloy.
