| Abstract: | The relation between laser texturing overlaid rate and 18-8 stainless steel fatigue life was analyzed by numerical simulation and related experiments. The result shows that the fatigue life of 18-8 stainless steel is improved after laser texturing treatment, and its fatigue property is better when the laser texturing overlaid rate is about 20%. |
