Mechanical and dry sliding wear behavior of Al7075 alloy-reinforced with SiC particles

In this article, the experimental results of the mechanical and tribological properties of Al7075-SiC composites are presented. The composites of Al7075 containing 2-6 wt% SiC were fabricated by liquid metallurgy route. The experimental results showed that the density of the composites increase with increased SiC contents and are in line with the values obtained by the rule of mixtures. The hardness and tensile strength of the Al7075-SiC composites are found to be increased by increased volume percentage of ceramic phase at the cost of reduced ductility. The wear properties of the composites containing SiC exhibited the superior wear-resistance properties.
