摘要	CrN coatings were deposited onto 38CrA substrate using arc ion plating (AIP) method. The microstructures of CrN coatings were investigated by XRD and SEM. The corrosion behaviour affected by deposition parameters was studied by salt spray corrosion test in a neutral mist of NaCl solution at (35 +/- 2) degrees C for 300 h. The results show that all of the CrN coatings contain primarily fcc-CrN along with hcp-Cr(2)N and bcc-Cr phases. CrN phase in coating deposited under lower N(2) pressure exhibited {100} preferred orientation, while {110} preferred orientation under higher N(2) pressure. Under the deposition condition of higher bias voltage and lower N(2) pressure, the CrN coating achieves dense microstructure with less residual stress and porosity, which leads to better corrosion resistance in salt spray test. The corrosion product of salt spray test was investigated by SEM and EDS, and the corrosion mechanism was discussed.
