【 摘 要 】

The article presents: the results of studies on the effects of cavitation on the surface of steel during processing in a liquid medium; the analysis of changes of the microstructure and the microhardness of steel under the effect of cavitation; the features of hardening and destruction of the surface layers of steel with a structure of granular pearlite and the martensitic steel structure. Comparative analysis of the structural transformations of the surface layers of steels 12H17 and U8 allows us to select the optimum time of ultrasonic treatment for a complete cleaning of the surface without destroying it.
