The surface of AISI 316 austenite stainless steel is modified by Plasma-based low energy nitrogen ion implantation. The phase structure is researched by X-ray diffraction analyzes. The correlation of pitting corrosion resistance and semiconductor properties for modified layer in 3.5% NaCl solution is investigated by the measurement of anodic polarization curves, electrochemical impedance spectroscopy and Mott-Schottky curves; and a suitable model is chosen by the fitting analysis of ZsimpWin software, the m...
