In order to improve the corrosion resistance and hemocompatibility of 316L stainless steel, mechanical polished 316L stainless steel was modified in situ by mixed acid (2%HF+10%HNO3, volume fraction) immersion and high-temperature treatment. The surface morphologies of 316L stainless steel and modified 316L stainless steel were characterized by X-ray diffraction (XRD), atom force microscopy (AFM) and scanning electron microscope with energy dispersion spectrometer (SEM-EDS). The corrosion resistance and wettability of 316L stainless steel and modified 316L stainless steel were analyzed by electrochemical and contact angle measurement respectively. The results indicated that Cr-O oxidation films were formed on 316L stainless steel after mixed acid immersion. Fe2O3 and Cr-O mixed oxidation films were grown on the high-temperature treatment 316L stainless steel. The corrosion resistance of modified 316L stainless steel was improved in simulated body fluid. The surface of 316L stainless steel modified by the two methods was hydrophilic. The surface energy polarization component of mixed acid immersion and high-temperature treatment 316L stainless steel were all increased. While, the interfacial tension between the materials and blood was decreased. Mixed acid passivation and high-temperature treated can improve the corrosion resistance and hemocompatibility properties of 316L stainless steel.
