  • Wear mechanisms of K2Ti4O9 whiskers reinforced Al-20Si aluminum matrix composites with lubrication of water and tetradecane

    • 摘要：

      The tribological properties of K2Ti4O9 whisker reinforced A1-20Si aluminum matrix composites were investigated in a mode of low amplitude reciprocal sliding. The ball-on-disk tests were performed at applied loads of 20-100 N and sliding velocity of 0.09 m s-1. The water lubricated composites demonstrated higher wear resistance and friction coefficient than the tetradecane lubricated composites did. The main wear mechanism is microgrooving at low applied loads and tribochemical wear at high applied loads for the pairs lubricated with water, microgrooving at all test loads for the pairs lubricated with tetradecane.
