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.

The purpose of this paper is to clarify the mechanism of a smooth surface generation in the ironing process under contact states with a largely relative slide. In this case, the outflow behavior of lubricant trapped in the oil pits is the most important point in the surface smoothing process. It was deduced from ironing experiments that lubricant flows out from oil pits as a result of plastic deformation of the metal surface layer, mainly in the friction direction. A model has been proposed to estimate variations in the friction stress during ironing. This model can explain experimental results that the metal surface is best smoothed under the condition in which the minimum friction stress appears.
