Abstract

This study investigates the microstructure and mechanical behavior of high-performance magnesium hybrid nanocomposites reinforced with aluminum oxide (Al₂O₃) and molybdenum disulfide (MoS₂) nanoparticles. Magnesum, recognized for its lightweight nature and high strength-to-weight ratio, is further enhanced by the inclusion of these nanofillers to improve mechanical properties such as tensile strength, hardness, and wear resistance. A stir casting method was employed to ensure uniform dispersion of the nanoparticles within the magnesium matrix, followed by a sol-gel coating process to enhance surface characteristics. Detailed microstructural analysis revealed effective grain refinement attributed to Al₂O₃, while MoS₂ contributed to improved tribological performance by reducing friction. The hybrid nanocomposites exhibited superior mechanical properties compared to unreinforced magnesium and those reinforced with a single type of nanoparticle. These findings underscore the potential of Mg-based hybrid nanocomposites in various applications, including automotive, aerospace, and biomedical sectors, providing an optimal combination of strength, wear resistance, and lightweight properties.
