Investigation of Wear and Mechanical Properties of Aluminium Hybrid Composites: Effect of Addition of SiC/B4C Through Casting Process

Aluminium is a binary alloy has a larger importance to engineering industries with excellent wear resistance and stiffness that have been designed for lightweight and higher strength applications in the automobile sectors. To synthesis the hybrid metal matrix composite, silicon carbide is chosen as primary reinforcement varied at different weight fraction (1, 2, 3, 4 wt%) with a constant boron carbide of 3 wt% used in the present study was carried through liquid metallurgy technique. The composites were then subjected to mechanical and wear properties study. The effect of reinforcement particles by increasing various weight fractions have been investigated and characterized mechanical and wear properties. The 4 wt% of SiC/B4C reinforced composites tends to increases hardness and tensile strength to 29.7% and 20% as compared to the base alloy.
