Method for forming nanometer gradient structure on surface layer of shaft metallic material

The invention relates to a surface treatment method for forming a nanometer gradient structure on a surface layer of a shaft metallic material. The invention aims to solve the problems that the surface roughness of the material to be treated is higher, the surface smoothness is not high and a nanometer crystal structure is difficult to form on the surface of a workpiece in the prior art. A spherical treatment tool is adopted to roll on the surface of the rotary shaft metallic material, and meanwhile, the spherical treatment tool moves along the axial direction of the workpiece, and plastic deformation is generated on the surface layer of the material, so that grains on the surface layer of a workpiece material are refined to form the nanometer gradient structure, wherein the depth of the deformation layer of the nanometer gradient structure reaches 100-300 micrometers; and the grains on the surface layer of the workpiece material are nanometer grains, submicron grains, deformation grains and initial grains in sequence in size from the surface to the inside. According to the processing method provided by the invention, the integral mechanical property of the material is improved through improving the microstructure of the surface layer, thereby, the service life of the material is prolonged. The processing method provided by the invention is small in investment and is simple and convenient in operation.
