Water cavitation peening (WCP) with aeration,that a new ventilation nozzle with aeration is adopted to improve the process capability of WCP by increasing the impact pressure induced by the bubble collapse on the surface of components.It has been verified that WCP with aeration can improve the process capability by the tremendous pressure.In this study,a standard N-type almen strips of spring steel SAE 1070 is treated by WCP with various fluxes of aeration and optimal standoff distances,and the arc height value is obtained,and the depth distributions of residual stress in the superficial layers is measured by X-ray diffraction method.The experimental results show that,the arc height value and the compressive residual stress distribution with various process conditions are different,and the optimal fluxes of aeration,the optimal standoff distances and the saturated time are achieved.Moreover,it indicates that the enhancement mechanism of WCP is different from the conventional shot peening.
