Abstract
Surface modification of 2Cr13 stainless steel was carried out using plasma immersion ion implantation (PIII) combined with ion beam enhanced deposition (IBED) technique. The chemical composition, concentration-depth profile of various elements were characterized by Auger Electron Spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). The microhardness, corrosion resistance, friction and wear behavior of the samples were evaluated. The results show that, titanium nitrogen (TiN) and chromium nitrogen (CrN) phase are existed in the surface layer. Compared with the substrate, the microhardness of the treated samples are enhanced significantly, the maximum is increased by 80.4%; friction coefficient is reduced to 0.2-0.3; wear track width and corrosion current density are decreased by 4 times and 26 times, respectively. Corrosion potential is increased by 5 times. The wear and corrosion properties are improved significantly by PIII-IBED techniques.
