... in maintaining wear resistance at 300 °C. However, at 500 °C, elevated oxidation and matrix softening increased the coefficient of friction until 100 m of sliding distance, where stabilization occurred. Hybrid ceramic reinforcement improved abrasive wear resistance and limited oxidation wear by reducing tribo...

Wear experiments have been conducted under dry sliding conditions at different operating loads (10, 20, 30, and 40 N) and sliding velocities (0.1, 0.2, 0.3, and 0.4 m/s) at room temperature. The incorporation of ZrO 2 nanoparticles improves the microhardness of the cast...
