| Advantages of Cavitation S Peening® |
 | Peened surface is extremely smooth (see Fig.3). |
| Shots are not necessary, i.e. Shotless peening. |
| It is easy to peen bottom of gear teeth and/or narrow region (see Fig.4). |
| There is no thermal effect to material surface. |
| Expensive plunger pumps are not required, since the impact force of cavitation bubble was used. |
| It is easy to control the peening area. pressure, nozzle size and injection time are same.) |
