Friction and Wear Behaviors of AI2O3 Based Ceramic Tool Materials at Temperatures up to 800°C
The friction and wear behaviors of Al2O3/TiC ceramic tool materials were evaluated at temperature up to 800 °C. The friction coefficient and wear rates were measured. The microstructural changes and the wear surface features were examined. Results showed that the temperature had an important effect on the friction and wear behaviors of Al2O3/TiC ceramics. The friction coefficient decreased with the increase of temperature, while the wear rates increased with the increase of temperature. The difference of the worn surface features of the Al2O3/TiC ceramics at different temperature is related to the chemical transformation during sliding wear tests. The wear mechanism of the composites at temperature less than 400 °C was primary abrasive wear, and the mechanisms of oxidative wear dominated in the case of 800 °C sliding operation.
