  • Aluminum (Al) 2024 matrix composites reinforced with alumina short fibers (Al2O3sf) and silicon carbide particles (SiCp) as wear-resistant materials were prepared by pressure infiltration in this study. Further, the effect of Al2O3sf on the friction and wear properties of the as-synthesized composites was systematically investigated, and the relationship between volume fraction and wear mechanism was discussed. The results showed that the addition of Al2O3sf, characterized by the ratio of Al2O3sf to SiCp, significantly affected the properties of the composites and resulted in changes in wear mechanisms. When the volume ratio of Al2O3sf to SiCp was increased from 0 to 1, the rate of wear mass loss (Km) and coefficients of friction (COFs) of the composites decreased, and the wear mechanisms were abrasive wear and furrow wear. When the volume ratio was increased from 1 to 3, the COF decreased continuously; however, the Km increased rapidly and the wear mechanism became adhesive wear.

      Abstract
    • Aluminum (Al) 2024 matrix composites reinforced with alumina short fibers (Al2O3sf) and silicon carbide particles (SiCp) as wear-resistant materials were prepared by pressure infiltration in this study. Further, the effect of Al2O3sf on the friction and wear properties of the as-synthesized composites was systematically investigated, and the relationship between volume fraction and wear mechanism was discussed. The results showed that the addition of Al2O3sf, characterized by the ratio of Al2O3sf to SiCp, significantly affected the properties of the composites and resulted in changes in wear mechanisms. When the volume ratio of Al2O3sf to SiCp was increased from 0 to 1, the rate of wear mass loss (Km) and coefficients of friction (COFs) of the composites decreased, and the wear mechanisms were abrasive wear and furrow wear. When the volume ratio was increased from 1 to 3, the COF decreased continuously; however, the Km increased rapidly and the wear mechanism became adhesive wear.
