Water—Air Mixing Jet Produced by Electro—hydraulic Impulse Technology Strengthening the Quality of Surface of Metal Materials

Electro-hydraulic impulse water-air mixing jet by which the quality of metal materials can be improved is described in this paper. The experimental results proved that the hardness and the micro-hardness of the surface layer of metal materials can be improved with this method, for example, the microhardness of CrWMn can be increased by 35.62 percent.
