Fabrication and Study on Impact of SiC Content and Wear Behavior of Aluminum Silicon Graphite Composite
摘要
Aluminum is a lightweight, structural metal that is widely used in the automotive industry. With certain restrictions, the silicon addition offers sufficient strength. Therefore, the goal was to incorporate hard particles like SiC. Also included as a multiple reinforcement is graphite. Composites made of aluminum matrix with many reinforcements (hybrid MMCs). MMCs are becoming more and more popular as alternatives to single-reinforced composites because of their better mechanical and tribological properties. The current research focuses on how the tribological behavior of aluminum matrix composites reinforced with silicon carbide (SiC) particles is affected by the inclusion of graphite (Gr) particles as a supplementary reinforcement. Stir casting was the technique used to create the castings. The presence of reinforcing particles in these produced composites was examined by microstructural analysis, SEM. Characterization clearly establishes the presence of reinforcements and their uniform distribution. Tests have shown that the mechanical qualities, such as tensile and hardness strengths, are superior to those of the basic alloy. To investigate the impact of SiC and graphite particles, wear experiments were conducted. The impact of graphite in the composite materials is confirmed by the wear test findings, which show that a lubricating coating forms at a weight of 4 kg.
