Aluminum matrix composites (AMCs) have attracted considerable attention in modern engineering applications due to their excellent strength-to-weight ratio, improved wear resistance, and enhanced mechanical properties. In this study, aluminum hybrid matrix composites reinforced with ceramic particles were fabricated using the stir casting technique. Reinforcement materials such as silicon nitride (Si₃N₄), aluminum nitride (AlN), zirconium boride (ZrB₂), fly ash, titanium diboride (TiB₂), and boron carbide (B₄C) were incorporated into the aluminum matrix to enhance mechanical and tribological properties. Mechanical characterization was performed through hardness, tensile strength, and compressive strength tests, while tribological behavior was evaluated using a pin-on-disc wear testing apparatus. Microstructural analysis was carried out using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD). Furthermore, the Taguchi method and analysis of variance (ANOVA) were applied to determine the most significant parameters affecting wear behavior. The results revealed that the incorporation of ceramic reinforcements significantly improved hardness, tensile strength, and wear resistance due to grain refinement and improved interfacial bonding between the matrix and reinforcement particles. The findings indicate that stir-cast aluminum hybrid composites possess excellent potential for advanced structural and tribological applications.
