Abstract

Plasma nitriding treatments of 304 austenitic stainless steel were performed at 400 ℃ for different time.Optical microscopy,surface profiler,EDX,X-ray diffraction (XRD),and microhardness tests were used to evaluate the surface morphology,microstructure,phase composition and properties of the nitrided layer.The results indicate that the surface roughness,nitrided depth,nitrogen concentration and microhardness of the nitrided samples increase with the increase of nitriding time.XRD patterns show that the nitrided layer formed at 400 ℃ for different time consists of S-phase only and no precipitation of chromium nitride.
