摘要	Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization procedures were used to investigate the pitting corrosion behaviors of AISI 316L stainless steel in the simulated body fluid, which was treated by high current pulsed electron beam (HCPEB). The results showed that the corrosion resistance of 316L samples was significantly improved after HCPEB treatment, which was demonstrated by the increase of polarization resistance (R,)) and decrease of interface capacitance. The samples after 5 pulses are prone to pitting due to the existence of remnant MnS inclusions or holes in the crater centers. Comparatively, the sample after 20 pulses of HCPEB treatment shows the best corrosion resistance. Its corrosion current density has been decreased to 1/15 of the initial samples, which can be attributed to the selective surface purification effect and removal of physical damages with increasing the number of pulses.
