Due to their high strength, superior wear resistance, high stiffness, and stability at high temperatures, metal matrix composites have been extensively used in applications related to the aerospace, automotive, communication, transport, marine engineering, and defence industries. Businesses have been concentrating on using innovative materials that give high strength to weight ratios, high stiffness to weight ratios, and desired wear resistance. In this study, stir casting was used to try to reinforce the graphite in the LM24 aluminium alloy, and response surface methods was used to assess and optimise the wear rate of the composite. Three parameters, including load, sliding distance, and sliding velocity, were chosen, and each parameter had three levels of variation. The tests will be conducted using 15 experimental designs based on the Box Behnken Design. Experimental evaluations of dry wear are conducted. Mathematical models were created and RSM-based optimization was used to lower the minimum wear rate. The wear rate on reinforced LM24 aluminium alloy with graphite is investigated using surface plots, and the best ideal solution is determined. The surface plot shows that 11 N load, 1 m/s sliding speed, and 2000 m sliding distance are the best process parameters for dry wear rate.
