Abstract:

This research focuses on evaluating the wear behavior of aluminum 7075 alloy reinforced with titanium diboride (TiB₂), zirconium dioxide (ZrO₂), and nanoclay to develop composites with enhanced wear resistance for industrial applications. The incorporation of these reinforcements improves the mechanical and tribological properties of the alloy by refining the microstructure and promoting uniform dispersion of hard ceramic particles. A total of 20 dry sliding wear tests were conducted, revealing that wear loss increases significantly with rising applied load. Among the influencing factors, ZrO₂ exhibited the highest contribution to reducing wear rate at 37.84%, followed by load (33.21%) and sliding speed (14.92%). Regression analysis confirmed that increasing ZrO₂ content, applied load, and sliding speed reduces wear rate due to improved hardness, grain refinement, and toughness. TiB₂ and nanoclay further enhance the load-bearing capacity and stability of the alloy under severe wear conditions. The synergistic effect of the reinforcements results in superior wear resistance, making the Al7075 hybrid composite a promising material for high-performance and wear-critical applications in the automotive, aerospace, and structural industries.
