Aluminum matrix composites are used in high-temperature applications such pistons, cylinder heads, and blocks for automobile engines. As a result, it's important to evaluate the performance of an aluminium metal matrix composite at high temperatures.in this study, we tried to find out the tribological behaviour of composite Al–SiC at elevated temperatures. The current study examines the wear behaviour of an Al–SiC composite with 20 percent SiC and 100 µm size powder reinforcement at different temperatures. The composite specimens are made using the centrifugal casting method, which results in considerable segregation of reinforcement on the composite's outer layer, which is exposed to wear. Response surface methodology (RSM) method is used to create experimental designs and for mathematical equation development. The wear test is carried out on a pin-on-disc device with a heating chamber.The study reveals that temperature has a significant impact on the rate of wear. The wear is predicted using a mathematical model based on regression. The scanning electron microscope (SEM) is used to investigate the worn-out surface, X ray diffraction (XRD) test were performed to analyse the purity and verification of particle size. The experiments are carried out in accordance with ASTM guidelines. As a result, at elevated temperature wear of composite increases as temperature increases and above 300 °C high wear have been obseved. According to ANOVA result, Temperature contributes 70.87%, load 4.51% and sliding distance 17.44% on wear. Temperature influence most if compare with sliding distance and load.
