The surface of the important mechanical parts such as the spring or the gear can obtain certain residual compressive stress on the surface layer of the material through the high-speed impact of the shot (generally adopting shot blasting) for strengthening, the residual stress can properly improve the fatigue fracture resistance of the material, but sometimes the integrity of the surface layer of the material can be further damaged due to smaller residual compressive stress or larger shot caused by undersize shot particles, so that the service life of the material can only be properly or possibly prolonged, and the latest research and practice of a large number of domestic and international metal materials proves that the surface of the important mechanical parts such as the spring or the gear can be strengthened through reasonable shot blasting, the integrity of the surface of the material is perfected, meanwhile, the residual compressive stress with a quite thick layer can be obtained on the surface layer of the material, and the residual stress and the integrity of the surface layer can obviously improve the fatigue fracture resistance of the material, thereby effectively prolonging the service life of the material. Researches show that the process needs to adopt the surface of a high-speed impact material with large-particle shots to form large residual compressive stress and peak value on the subsurface (usually 30-75 um), then uses the surface of the high-speed impact material with small-particle shots to form proper residual compressive stress and peak value on the surface (usually 15-30 um), and simultaneously repairs and modifies crystal grains and microcracks on the surface of the material, thereby effectively prolonging the service life of the material.
