Recently, the high-speed submerged water-jet peening using the high impact pressures being accompanied by the bubble collapse is attracting attention. In this study, therefore, in order to improve such a peening effect and to make rapid progress of the applicable range, we take up a typical water-jet accompanied by uniformly large bubble-cloud, the time dependent change of residual stress is systematically measured on the gear surface by means of the X-ray diffraction method for a complex mechanical part of complicated shape (single helical gear of SCr420H3V2L2 carbon steel), and the definite peening effectiveness has been verified. We show on the surface that the residual tensile stress can be effectively improved into the residual compressive stress. It is also confirmed that uniform peening effect well works even for such very complex parts.
