| Abstract: | It is suggested that the controlled shot peening can be used for impairing cavitation intensity and slackening development of cavitation. The controlled shot peening is an effective method for improving the anti fatigue intensity of the material surface. If the passage of the turbine is dealt with the shot peening, the anti cavitation character of the turbine will be improved, and the service life of the turbine passage parts will be prolonged. |
