The high power density, Nd:Glass laser shocking system with five-axes NC worktable was used to shock the fillet of main and rod surface of crankshafts. In the experiment, the parameters of laser shock processing are as follow: laser wavelength was 1.06 μm, pulse duration was 23 ns and output power ranged from 25～40 J. Flowing water and the ethyl silicate materials was used as confinement layer and absorbing medium respectively. Residual stress, hardness and wearability of the laser shocked surface were investigated as functions of laser processing parameters. The results show that the shocked zone has no obvious macro deformation,but the hardness and compressive stress of the laser processed surface was significantly enhanced,the wearability was increased about 1.4 times compared with those without LSP, which is favorable for the fatigue properties of crankshafts.
