An extensive investigation is conducted on Mg-based composites reinforced with various sorts of particles, which are manufactured by stir casting. The materials under examination include AZ31, AZX915, and AZ91 alloys, which have been strengthened with fly ash, TiC, Gr, (B4C), and carbon nanotubes. The wear behavior, mechanical characteristics, and microstructural properties of these composites are analyzed under different loads and circumstances. The findings indicate that the choice and concentration of strengthening significantly impact WRs, COF, and mechanical strength. Multiple wear mechanisms, including as abrasion, tribo-oxidation, and delamination, are acknowledged. The investigation is currently focused on the application of advanced techniques, including as vacuum SCTand ultrasonic-assisted solidification processing, to enhance the characteristics of materials. In addition, research investigates the synergistic benefits of different strengthenings, such as the combination of hard particles (TiC, B4C) and soft particles (Gr), to enhance WR. It emphasizes the significance of tribological elements, such as load, velocity, and SD. Decision trees have demonstrated effectiveness in predictive modeling when employed in machine learning models. The study contributes valuable insights to the progress of MMC that exhibit enhanced mechanical and tribological properties. The automotive and aerospace engineering sectors may find use for these composites.
