Method of surface self-nanocrystallization of metallic materials
The present invention relates to a method of surface treatment of metallic materials, more particularly, to a method of the surface self-nanocrystallization of metallic materials by the bombarding of supersonic fine particles. The method comprises the step of bombarding the surface of metallic substrate material with fine particles at supersonic speed of 300-1200 m/s carried by a compressed gas, which is ejected from a nozzle. The present method can be used for the surface self-nanocrystallization of metallic parts with a complicated structure or a large area, and the nanometer layer obtained is homogeneous. In addition, it can be operated in a simple way with low energy consumption, low cost, high efficiency of production and high surface nanocrystallization rate of from 1 cm2 to 10 cm2/min.
