Effect of eutectic silicon and silicon carbide particles on high stress scratching wear of aluminium composite for various testing parameters

Abstract In the present investigation, the mechanism of material removal with the help of mechanically mixed layer has been evaluated. The effect of different experimental parameters has been evaluated on aluminium matrix alloy (ADC12) and it's composite (ADC12 + 10%SiC). For the investigation of material removal, the reinforcement size is taken as 45 to 80 μm, applied load as 2 N, 6 N, 10 N, abrasive size as 30 μm, 50 μm, 70 μm and sliding distance of 40 m, 60 m, 80 m, 100 m with 500 rpm. In the present observation, the hardness of composite is found to be better than the alloy. In addition, wear resistance of composite has been found better than the alloy. Mechanically mixed layer was formed for low load. For high load, mechanically mixed layer was not found. Maximum wear resistance of material was found for fine abrasive and low load and transition of material removal was found for high abrasive size.
