A STUDY OF THE INFLUENCE OF CAVITATION STRUCTURES ON THE FACIAL LAYERS OF STRUCTURAL MATERIALS

Abstract

The effect of ultrasonic cavitation is widely used in some technological processes, for example, ultrasonic cleaning. Along with the positive effects, cavitation leads to deformation and destruction (erosion) of treated materials’ surface. Controlling the effects caused by ultrasound in a liquid requires a detailed study of the cavitation structures’ impact on the facial layers of work-pieces. Proposed methodology includes the processing of metal samples in liquid under the impact of ultrasonic field. The process dynamics were recorded using high-speed video camera. Samples’ characteristics were measured before and after treatment. The article presents a study on the effect of cavitation structures on the facial layers of structural materials, as well as modification regularities of physical, mechanical, and geometrical parameters of the metal sample surfaces under the impact of cavitation. The authors revealed the quantitative characteristics of structure transformations, as well as changes in microhardness, roughness, and subroughness of the samples.
