Investigation of the Effects of Process Parameters on Metal Matrix Composites of A356 with SiC on Mechanical and Tribological Characteristics

Aluminum alloys are becoming more and more utilized in the aerospace and automotive sectors due to their lightweight characteristics, outstanding mechanical capabilities, and relatively high resistance to corrosion. This study examines the vital mechanical properties of metal matrix composites from A356 aluminum alloy that are strengthened with silicon carbide (SiC) particles. A356 aluminum alloy is widely utilized in various engineering applications, and the incorporation of SiC as a reinforcing phase aims to enhance the mechanical properties. This research focuses on the casting of A356 alloy and SiC composites using different processing techniques and varying SiC particle volume fractions from 0.25% to 0.75%. The efficacy of SiC reinforcement is assessed by systematically evaluating mechanical parameters hardness and tensile strength. Additionally, wear resistance of the samples were investigated under different loading conditions and sliding velocities. Microstructural analysis techniques, such as microscopy and scanning electron microscopy, provide insights into the interfacial bonding and dispersion of SiC within the aluminum matrix. The results from this paper contribute to the understanding of the synergistic effects between A356 aluminum and SiC reinforcements, offering valuable insights for the optimization of composite materials in engineering applications requiring enhanced mechanical and wear performance.
