Dynamics of Surface Properties of Steel Kh12MF During Cavitation-Erosion Treatment

The results of studies on the surface of Kh12MF steel following exposure to ultrasonic treatment in a liquid medium are presented. The microhardness, roughness parameters, structure, and submicron structure of surface layers are determined. The mechanism of erosion is revealed along with its correlation with the parameters of micro- and submicron geometry of the sample surface. The possibility of using liquid ultrasonic treatment to improve the properties of heavy-duty materials and components having complex geometry is established.
