An Investigation on Mechanical and Wear Characteristics of Al 6063/TiC Metal Matrix Composites Using RSM

This paper focuses on the consequences of reinforcement content (TiC particles) on sliding wear behavior of aluminum alloy Al 6063 fabricated by stir casting process. Three different reinforcement percentages (5, 10 and 15) have been considered in the present study. Both hardness and tensile tests have been executed on the fabricated samples. The results of the conducted mechanical tests showed that the increase in reinforcement weight percent increased the tensile strength and hardness. Pin-on-disk tests have been performed on the fabricated composite samples to identify their tribological behavior. Reinforcement weight percent, load and sliding speed with three levels each were taken as the process variables, and specific wear rate is considered as response. Box–Behnken design have been utilized to carry out the experiments and to analyze the results. Moreover, ANOVA is carried out to know the influencing parameter on the response. From ANOVA, it was confirmed that reinforcement weight percent and sliding speed is considered as the influencing parameters on the response.
