Abstract:

Effects of Laser Shock Peening (LSP) with different coverage layers on Corrosion Fatigue (CF) resistance of 2Cr13 stainless steel were investigated by residual stress measuring, CF testing and fatigue fracture morphology observing. The results show that LSP can induce high compressive residual stress on the surface of 2Cr13 stainless steel, and the value of surface compressive residual stress increases with the LSP coverage layer. The CF life of LSP specimens is much larger than that of as?machined specimens, and it increases with the LSP coverage layers. The CF crack growth rate of LSP specimens decreases compared with that of as?machined specimens, and it decreases with the LSP coverage layers. After the analysis, we can conclude that the fatigue fracture surface of as?machined specimens is flat and contains few secondary cracks. However, for LSP specimens, due to high surface compressive residual stress induced by laser shock peening, the growth of CF crack is effectively restrained, resulting in a river pattern morphology.
