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.
