  • 摘要:The role of engineering materials in the development of modern technology like Metal MatrixComposites (MMCs) have evoked a keen interest in recent times for potential applications in aerospace and automotiveindustries owing to their superior strength to weight ratio and high temperature resistance. Aluminium (2024) and SiC(320-grit) has been chosen as matrix and reinforcement material respectively. In this present study an attempt is madeto develop Aluminium based silicon carbide particulate MMCs. Stir casting is one of the most economical method ofprocessing MMC and to obtain homogenous dispersion of ceramic material. Al–SiC composites containing differentweight percentages 10% and 15% of SiC have been fabricated by liquid metallurgy method. Experiments areconducted by varying weight fraction of SiC (10%, 15%), while keeping all other parameters constant. The distributionof reinforcement and percentage of composition are tested by Energy-dispersive x-ray spectroscopy. Hardness of theMMCs are measured by Rockwell hardness method. Experiments are planned to conduct Friction and wearcharacteristics of Al–SiC composites have to be investigated under dry sliding conditions carried out using pin-ondiskwear test for rating normal loads and keeping all other parameters constant. Weight loss of samples has to bemeasured and the variation of cumulative wear loss with sliding distance has to been found for the composites.The best results would be observed at % weight fraction of 320 grit size SiC particles for minimum wear and thesuperior weight percentage of reinforcement is identified for tribological applications.
