【 摘 要 】

The article describes a study of cavitation in the border areas of the vibrational tools and static solid of ultrasonic field. A high-speed camera Fastcam SA-X2 version 1000K which is able to shoot up to 1 million frames per second with electronic shutter 283 ns was used for a more practical covering of the processes occurring in the cavitation bubble at collapse near a solid surface, as well as on the possibility of fixing the cumulative impact of a collapsed bubble to the surface. The studies of cavitation resistance materials peening methods, failure of which could be due to the cumulative effect or cavitation bubbles collapse in the immediate vicinity of the sample can be used to optimize the choice of emitter material operating in corrosive liquid environments.
