The influence of high current pulsed electron beam treatment on the corrosion resistance of magnesium alloy AZ31 was investigated based on measurement of potentiodynamic polarization curve,observation of optical mi-croscope,and analysis of electron probe.The morphologies and elemental compositions of the modified specimens were analyzed as well.Results indicated that the corrosion resistance in 5 wt% NaCl solution of the specimens treated with pulsed electron beam at an accelerating potential of 27 kV for 8...
