N2 - Mo-N hard coatings on Ti6Al4V were formed using double glow discharge technique. The fundamental coating properties, such as the phase, hardness and elastic modulus were investigated. The tribological performances of the coating in the dry wear condition were studied by means of ball-on-disc wear machine. The experimental results show that the thickness of the Mo-N hard coating is about 10 μm. The coating is single fcc γ-Mo2N phase with (200) preferred orientation. The hardness and the elastic modulus of the coating were 13.80 GPa and 261.65 GPa respectively. The surface treatment enhances the hardness and the elastic modulus of the surface of Ti6Al4V base greatly. With GCr15 slider ball, the friction coefficient of the Mo-N hard coating is in the range of 0.56-0.65 at the steady state. Though the coating does not show the friction reducing effect, it improved the wear resistance of Ti6Al4V greatly.
