Abstract
In present paper, the dry sliding wear behaviors of wrought Al-12.7Si-0.7Mg alloy have been investigated using a pin-on-disc machine. The effect of various parameters, such as alloy conditions, sliding speed, and normal pressure, has been investigated. Wear surface was characterized
by SEM/EDX microanalysis. The microstructure, hardness and tensile properties of the extruded profile were investigated with the aim of understanding the wear and friction mechanisms. The present results reveal an improvement in the mechanical and tribological properties, obtained due to microstructure
characterized by fine Si particles uniformly distributed in the Al matrix of fine equiaxed grains, as promoted by hot extrusion. It was also revealed that higher hardness and the lower aspect ratio of eutectic Si particles contributed to the better wear resistance.
