“…The harder deformation of the counter surface penetrates the softer pin surface more as the applied stress increases. After each composite's critical load [18], with the application of load, the wear rate quickly starts to rise when the applied load increases to 20 N. The load at 30N the wear rate spikes to a very high level. In the event that the transitional load and the velocity of the composite increases in value by a large margin.…”

A tribological investigation was undertaken on hybrid metal matrix composites based on Aluminum alloy 6262, incorporating varying weight percentages of Tungsten Carbide (WC) and Molybdenum disulfide (MoS2) under dry sliding conditions. Specifically, Tungsten Carbide was incorporated at 3%, 6%, and 9%, while Molybdenum disulphide was introduced at 2%, 4%, and 6%. The fabrication of these hybrid composites was accomplished using the stir casting technique. The experimental design followed an L27 orthogonal array, and Taguchi optimization was employed to identify the optimal combination of input parameters. The orthogonal array, signal-to-noise ratio and analysis of variance were employed to study the optimal testing parameters on developed composites. The optimal formulation, resulting in the minimum wear rate and coefficient of friction, was determined to be 9% WC, 6% MoS2, a load of 10N, a sliding velocity of 1 m/s, and a sliding distance of 400 m. Characterization was carried out for Al6262/WC/MoS2 hybrid composite by using scanning electron microscopy (SEM).
