摘 要：In this paper, a running cost is cheap from the thing used for harmless peening treatment to the environment,health which an influence is rare in toward processing material like heat being only water fundamentally, and economical,and the characteristics is hard to get are given. There is some research about the residual stress improvement by water-jet peening during the high-speed water. In this study, a big bubble cloud ceremony water-jet peening which dissolves the problem of the form of the applicable thing by exposing the whole of the applicable thing in the big bubble cloud as the way of dealing with peening efficiently in a short time is proposed by this research. Moreover, the uniform compression residual stress is added around the surface of the processing side, and connected with the remarkable improvement of the fatigue strength of the part. Furthermore, and safety processing is very possible, and it thinks about the thing which has possible high practical use, and writers to get rid of the problems of the way of processing it with peening until now. Water-jet peening was given by this research during high-speed water with big bubble cloud-type water toward tooth gear manufactured by SCr420H3V2 to open the effect of water-jet peening during the high-speed water. A change was measured at the time as the sutra of the residual stress on the surface of the test settlement by the X-ray method, and the validity of this law was verified.
