AbstractAn extremely simple and environmentally friendly water treatment was developed to enhance the general corrosion resistance of biomedical high nitrogen nickel-free stainless steels (HNNFS). After treatment, the corrosion rate of HNNFS could dramatically reduce to 1/20 of the untreated in 37 degrees C 0.9 wt% NaCl solutions. Then the passive film on HNNFS was analyzed by electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectroscopy (XPS). It was found that Cr enrichment and thickness increase of passive film contributed to the improvement of general corrosion resistance of HNNFS. (C) 2019 Elsevier B.V. All rights reserved.
