Statistical Analysis on Wear Behavior of Aluminum Alloy2024–Silicon Carbide–Fly Ash Metal Matrix Composites 2024-01-5058

Aluminum and its alloys entered a main role in the engineering sectors because of their applicable characteristics for indispensable applications. To enhance requisite belongings for the components, the composition of variant metal/nonmetal with light metal alloys is essential in the manufacturing industries. To enhance the wear resistance with significant strength property of the aluminum alloy 2024, the reinforcement SiC and fly ash (FA) were added with the designation Al2024 + 10% SiC; Al2024 + 5% SiC + 5% FA; and Al2024 + 10% FA via stir-casting technique. The wear resistance property of the composites was tested in pin-on-disc with a dry-sliding wear test procedure. The experiment trials were designed in Box–Behnken design (BBD) by differing the wear test parameters like % of reinforcement, sliding distance (m), and load (N). The wear tests on casted samples were carried out at the constant velocity of 2 m/sec, such that the corresponding wear rate for the experiment trials was recorded. Analysis of variance (ANOVA) determined that the Al2024 + 5% SiC + 5% FA, sliding distance 700 m, and load 30 N is the favorable to improve the wear-resisting property of the aluminum alloy hybrid composites. The distance of the composites traveled implies a significant contribution to wear rate with the follow of reinforcement composition rate and external load. The dynamic components are fabricated as hybrid composites directed to operate with this limit of wear-generating parameters.
