Abstract

40Cr steel substrate is coated with TiAlN/TiN films by Multi-arc ion technology. The properties of sliding friction and wear on the surfaces of TiAlN/TiN films and substrate are tested by using the machine of friction and wear. The carrying capacity and tribological properties are investigated. The surface morphology of wear specimens is observed and the elements of wear scar center are analyzed. The results show that the friction coefficient of TiAlN/TiN films is lower than 40Cr under the same conditions. The wear scar of TiAlN/TiN films is lower and the wear loss is fewer than 40Cr. The TiAlN/TiN films can successfully reduce friction and wear resistance.
