THE INFLUENCE OF FREQUENCY OF VIBRATIONS OF ULTRASONIC HARDENING TOOL ON THE PROPERTIES OF THE TREATED SURFACE
Ultrasonic surface-plastic deformation is an effective way of forming properties of the surface layer of the workpiece. Currently, in the literature practically there are no data on the influence of frequency fluctuations on the efficiency of the process of hardening. The article presents the results of studies on the influence of frequency of ultrasonic strengthening processing associated with the indenter on the roughness and microhardness of the treated surface.
