For developing thin film materials with excellent friction and wear resistance, TiAlN thin films were deposited on the surface of 4Cr13 martensitic stainless steel by multi-arc ion plating, and TiAlN thin films doped with Cr and Cr-Ni were deposited on the surface of 4Cr13 by magnetron sputtering and multi arc ion plating, respectively.Scanning electron microscope(SEM), X-ray diffractometer(XRD)and Vickers hardness tester were used to analyze the surface morphology, phase and surface hardness of the film.The surface morphology, composition and phase of the worn film at different temperatures were analyzed.Results showed that the surface hardness of the film decreased after doped with Cr and Ni.As the temperature increased, the friction coefficient of the three films decreased.Moreover, the friction coefficient of the TiAlN film co-doped with Cr and Ni was the smallest at each temperature, followed by Cr-doped TiAlN film, which showed that the addition of Cr and Ni was beneficial to decrease the friction coefficient of the material.After friction at 100 ℃ and 300 ℃, the wear amount of undoped TiAlN film was higher than those after doping, and the wear amount of TiAlN films co-doped with Cr and Ni was the lowest.When the friction temperature increased to 500 ℃, the wear amount of TiAlN films was lower than that of doped films.
