Abstract

In this paper, the effect of wear parameters on the wear rate of AA5086 alloy reinforced with Alumina (Al2O3) and Titanium boride (TiB2) is investigated. The Al2O3 content is fixed at 5wt%, while the variation in TiB2 content is considered as one of the parameters. The preparation of AA5086/Al2O3/TiB2 hybrid nano composite is carried out using the stir casting technique. To formulate the experimental design, response surface methodology (RSM) is employed, and four factors at three levels are selected using the Box Behnken design. The chosen process parameters include reinforcement wt% (5%, 7.5%, 10%), load (30N, 40N, 50N), sliding speed (500rpm, 600rpm, 700rpm), and sliding distance (400m, 450m, 500m).The results indicate that the highest wear rate of 0.09876 mm3/Nm is observed when using a load of 50N, sliding speed of 500 rpm, sliding distance of 400m, and a reinforcement content of 5%.An analysis of variance (ANOVA) is performed to determine the significance of each factor on the wear rate. According to the ANOVA results, it is found that load is the most critical factor contributing to the increase in wear rate, followed by sliding distance, sliding speed, and reinforcement content.
