Abstract
The tribological properties of TiN coating were studied at the speed of 40m/min-120m/min, under the load of 5N-15N at elevated temperatures between 200°C-600°C. It can be concluded that when the temperature is lower than 400°C, the coefficient of friction increased with temperature, but the value decreased because of the friction oxidation at 600°C.The wear mass loss of the coating increased with increasing of speeds and loads, and this proved the TiN coating was not adaptable to high temperature environment. The wear mechanisms of TiN coating at elevated temperature were abrasive wear, plastic deformation, oxidation wear and adhesion wear.
