钢球表面形变强化工艺，是提高钢球质量的一个重要手段。试验结果表明，钢球热处理后，经过表面形变强化处理，对提高钢球的表面硬度、终加工的表面质量和接触疲劳寿命的效果十分明显。 Steel ball surface deformation strengthening process, is to improve the quality of the ball an important means. The test results show that after the ball heat treatment, after the surface deformation strengthening treatment, to improve the surface hardness of the steel ball, the final surface quality and contact fatigue life effect is very obvious.
