Need of global development in research, industries and defense applications promote researchers to deal with composites. This paper aims to analyze all the tribomechanical characteristics by fabricating aluminum (Al) alloy altering the volume percentage of reinforcements like silicon carbide (SiC), waste carbonized egg shells (WCE) and boron carbide (B4C) by stir casting. Experimental results shows increase of tensile strength, fatigue strength and hardness up to 12.5 wt.% in Al matrix alloy, but then decreases. Also toughness and ductility decreases at the same reinforcement conditions. Heat treatment was done to improve the corrosion rate of the composites. The results inferred that using WCE gave better physical and mechanical properties at lower cost than uncarbonized egg shells (ES) or SiC or B4C.

This paper aims to analyze all the tribomechanical characteristics by fabricating aluminum (Al) alloy altering the volume percentage of reinforcements like silicon carbide (SiC), waste carbonized egg shells (WCE) and boron carbide (B4C) by stir casting. Experimental results shows increase of tensile strength, fatigue strength and hardness up to 12.5 wt.% in Al matrix alloy, but then decreases. Also toughness and ductility decreases at the same reinforcement conditions. Heat treatment was done to improve the corrosion rate of the composites. The results inferred that using WCE gave better physical and mechanical properties at lower cost than uncarbonized egg shells (ES) or SiC or B4C.
