Design and optimization the wear characteristics for Al7178/TiO2/B4C/FA central hybrid composite

In this research process, Al 7178 is considered as base material, boron carbide (B4C), Titanium dioxide and Flyash are utilized as reinforcement elements to improve the wear behavior. The sample of the composite is prepared by Stir casting method. The amount of all reinforcements (3%) is constant. As per the central composite design, wear tests are performed on pin on disc apparatus with alteration of factors level. The chosen factors are load (15 N, 25, 35 N) and sliding speed (3, 6 and 9 m/s) and sliding distance (350, 400, 450 m). The observation experiment results shows that Maximum wear rate is recorded as 0.01582 mm3/Nm for a load of 25 N, slide distance of 400 m and slide speed of 6 m/s. The minimum Wear rate is attained as 0.00748 mm3/Nm at parameters combinations of 35N, 450 m and 9 m/s. Analysis of variance (ANOVA) showed that load, and the interaction between load and sliding distance have the most significant parameters on wear rate trailed by sliding speed.
