Titanium nitride (TiN) film as a hard material is omnipresent, and plays a crucial role in extensive engineering and functional applications. The friction coefficient of TiN film is generally high (0.5–0.8) in atmospheric environment, and the coefficient of friction in vacuum is predicted to be higher based on adsorption theory and lack of heat transfer media. At present, we investigate the tribological behavior of TiN film in atmosphere and vacuum environments. Counterintuitively, the average friction coefficient is 0.58 at ambient air, while that in vacuum is 0.31. One reason is that the reduction of oxygen content can effectively inhibit oxidation and form low friction at the sliding interface. Meanwhile, the electrostatic repulsion generated by the nitrogen atoms on the surface of TiN film is another reason for the low friction. The results indicate that TiN film has a potential feasibility application in vacuum environment.
