Импульсная электролитно-плазменная технология размерной и финишной обработки металлических материалов

Abstract

To reduce energy consumption and increase the efficiency of the process of electrolytic plasma treatment (EPT) for the purpose of modifying and polishing the surface of products made of metallic materials, their dimensional processing while maintaining high intensity, processing quality and environmental safety, a new pulse method has been developed that combines the advantages of both electrochemical and and electrolytic-plasma process. The method is based on the use of a unipolar pulsed mode with a pulse duration of 0.5–10 ms and an amplitude of more than 200 V, in which the electrochemical stage, the transitional stage, and the stable EPO stage alternate sequentially within each pulse. An increase in the efficiency of the developed process is achieved due to the main intensive metal removal during the implementation of the electrochemical stage with low energy costs and optimization of the duration of the electrolytic-plasma stage, which ensures high surface quality.
