The Investigation of Composition and Corrosion Resistance of PIII Nitrided M50 Steel

Article Preview

The evolution of composition and corrosion resistance of PIII nitrided M50 steel with various process parameters was investigated. Besides nitrogen, the oxygen also was detected in modified layer, which came from the H2O and CO2 desorbed from chamber walls at high temperature. The results show that the content and diffusion distance of oxygen and nitrogen increase with temperature firstly; while the temperature exceeds 350 , the content and diffusion distance of oxygen and nitrogen reduce dramatically, because of the external diffusion of oxygen and nitrogen in form of NOx gas. The implantation current density is beneficial to increase the content and diffusion distance of oxygen and nitrogen. The corrosion tests show that the sample with higher oxygen and nitrogen content has better corrosion resistance.
