ULTRASOUND EFFECT ON MOLTEN METAL PROPAGATION INTO SUBMICRON PARTICLES AND THEIR AGGLOMERATES

Abstract
Based on the theory of acoustic cavitation and capillary phenomena, the article considers the processes of deagglomeration and wetting of submicron particles in a metal melt under ultrasound exposure. Basic dependences were found that link the exposure time to the physical and chemical properties of particles and melt, and to acoustic radiation characteristics. Experimental and calculated time values of ultrasonic treatment of aluminum melt containing submicron particles of aluminum oxide were compared, and the obtained results were found satisfactorily fit.
