Rapid surface alloying Al on the surface of AZ31 alloy by high current pulsed electronic beam was conducted, and microstructure of alloying layer on the surface was observed, meanwhile, corrosion resistance and wear resistance of the AZ31 magnesium alloy after and before alloying Al were examined. The results indicate that typical crater can be observed on the surface after HCPEB bombardment. Compared with that of initial sample, the relative wear resistance of the sample with accelerating voltage of 27kV and five times pulse is increased by 6 times. In addition, the corrosion resistance of AZ31 magnesium alloy after alloying Al is greatly improved in 5% NaCl solution.
