Abstract: Nano-multilayer coatings havebeen widely applied in wear-corrosion protection of titanium alloys. In this paper, TiN, CrN and TiN/CrN nano-multilayer coatings were prepared on the surface of TC4 alloy by arc ion plating technology. The microstructure, phase structure, hardness, adhesion strength, wear and electrochemical corrosion properties of the coatings were systematically studied. The results showed that the TiN/CrN nano-multilayer coating grew with (111) preferred orientation, a dense structure, a modulation period of 25 nm and a hardness of 24 GPa. The multilayer structure interrupted the growth of the columnar crystal and effectively blocked the channel of the corrosion medium diffusing to the substrate. Compared with TiN and CrN coatings, the adhesion strength of TiN/CrN coating with TC4 was significantly improved. The wear rate of TiN/CrN coating was 3.44×10-7 mm3·N-1·m-1, and the self-corrosion current density (icorr) was 3.16×10-8 A/cm2, which were significantly lower than those of TC4, TiN and CrN coatings, indicating that the wear and corrosion resistance of TiN/CrN nano-multilayer coating were better than those of TiN and CrN coatings, and it could provide better protection for TC4 alloy under wear-corrosion environment.
