One of the most efficient methods for parts cleaning is an ultrasonic method. During ultrasonic influence on of the most significant factors defining cleaning quality is oscillation amplitude. The paper reports the formulation of the conclusion on the presence in a sound field a high-amplitude radiation formed in liquid by a piston radiator of three (technological) cavitation areas different their effectiveness.

A review of technologies with the use of ultrasound not only used successfully at present, but a number of processes under development is carried out. Their high productivity is provided with the combination of the known methods with ultrasound impact. At that there are summarized not only positive phenomena of each of the processes, but a synergetic effect becomes stronger due to their integration.
