Abstract:  
Cavitation S Peening ® is a peening method that uses cavitation impacts to improve fatigue strength and/or to introduce compressive residual stress. The peening method using cavitation impact is called “cavitation shotless peening (CSP)”, as shots are not required (see Fig. 1). In the case of cavitation shotless peening, cavitation is generated by cavitating jet.
