EROSION OF THE PRODUCT DURING ELECTROLYTE-PLASMA POLISHING

Abstract

It is well known that electrolyte-plasma polishing is one of the promising methods of finishing parts, which allows to increase the roughness class several times. At the same time, the geometric complexity of the treated surface is practically unlimited, which is extremely important due to the trends in the use of parts of complex spatial configuration obtained by additive manufacturing methods. The presented article in this regard is devoted to the study of the possibilities, potential and prospects of using the method of electrolyte-plasma polishing. The paper argues that it is necessary to carefully approach the choice of processing parameters, since an unreasonable choice of a number of values of technological parameters can lead not only to the absence of a decrease in roughness, but also to a change in the properties of the material, as well as damage and rejection of the product. The article presents the results of experiments to identify the defect of electrolyte-plasma polishing in the form of erosion of the surface of the material of the processed product. In the conclusion of the article, based on experimental data, the processing parameters at which such defects occur are established. The assumptions about the possible causes of this phenomenon are presented, as well as the prospects for continuing research and the most relevant areas of application of the results are considered.
