A strong pulse electromagnetic field was employed to treat the surface layer of several metal materials. The results showed that the treatment of the strong pulse electromagnetic field could modify the microstructure of the region around the crack on the 45# steel surface. It could also make the recovery process occur in the scratch on the brass surface, and make the surface layer of the Wood’s alloy melt in a very shot time. These results indicated that the strong electromagnetic pulse could be developed as an effective non-contact method for the metal surface processing.
