Development of advanced hybrid ZA43–Gr–SiC composite with improved mechanical properties for sustainable transportation applications

The development of high-strength-weight ratio and wear resistant metal matrix composites (MMCs) has demanded due to the requirements imposed by the transportation sector for light, high- performance and environmentally friendly materials. Due to its good castability, the corrosion resistance and properties as bearing are excellent in zinc-aluminum alloy ZA43. However, ZA43 is known to have a strength that is too low, deteriorating under high temperature conditions. To address these issues, this work utilizes silicon carbide (SiC) and graphite (Gr) as reinforcements for ZA43. The microstructural analysis showed that the reinforcements were spread out evenly throughout the material. The mechanical testing showed that the tensile strength, hardness, and toughness were all higher than those of mono ZA43. The findings suggest that ZA43– Gr–SiC hybrid composites could be advantageous for environmentally sustainable transportation systems that necessitate durable, lightweight materials.
