摘要：
A Ti/TiN/Zr/ZrN multilayer film was prepared on 1Cr17Ni2 stainless steel by vacuum arc deposition, and the morphologies, phase composition, bonding strength, polarization curve and electrochemical impedance spectroscopy (EIS) of the multilayer film were studied. The results show that the film is mainly composed of TiN and ZrN phases with some metal Ti and Zr. The multi-element interface of the Ti/TiN/Zr/ZrN multilayer film is excellent and dense with a total thickness of 2 similar to 3 mu m, and the grain size is uniform and fine. The bonding strength between the film and the substrate is higher than 70 N. The microhardness HV0.025 of the films is up to 29000 MPa. Compared to the uncoated 1Cr17Ni2, the multilayer film possesses higher corrosion potential, higher polarization resistance, larger capacitive reactance arc and lower corrosion current density.
