Abstract

Abstract: 315 austenitic stainless steel was nitrided respectively at 400, 440, and 480 ℃ for 12 h, and then the physicalvapour deposition (PVD) and CrN film coating were carried out for the nitrided samples. The surface morphology, cross-section morphology, composition, microhardness, wear resistance, and corrosion resistance of the compositely modifying layer were tested by means of scanning electron microscope(SEM), optical microscope(OM) and X-ray diffractometer (XRD), Vickers hardness tester, material surface tester(HSR-2M), and electrochemical workstation. The result showed that the sample with ion nitriding at 400 ℃/CrN film coating would exhibit the best corrosion resistance and the worst wear resistance; the sample with ion nitriding at 480 ℃/CrN film coating would have the worst corrosion resistance and the best wear resistance, but its performance would better than that of a sample nitrided only at the same temperature.

Key words: 316 austenitic stainless steel, nitriding, physical vapour deposition(PVD), CrNfilm
