The Mass Transfer Intensification of Combined Treatment Products

Abstract

The paper addresses the issues, related to mass transfer of treatment products when using combined forming methods with the application of an electric field. The impact of process components upon strength characteristics of parts has been shown. We have discovered the dependence of allowance removal rate upon the quality of preparation of the reference workpiece surface. The article describes the available industrial and newly developed methods of mass transfer intensification, using the original kinematics of movement, the improvement of the geometrical shape, the position of electrode-tools and the application of various options in the flow of liquid working media, including the cavitational mode, described in detail for the first time. We have disclosed the mechanism of the impulse effect upon treatment products, ejected from the inter-electrode gap by the liquid working medium. The issues have been discussed, concerning the hydrodynamic instability of liquid working media flow, impacting the intensity of mass transfer, with limitations, caused by the impact of side surfaces of holes and channels when processing with a profiled and a non-profiled wire electrode-tool. We have shown the impact of a concentrated ultrasonic beam upon mass transfer of treatment products, formed at a great distance from the electrode.
