The article discusses technological aspects of using jet focused electrolytic plasma treatment on the example of a part such as a flange made of steel 45Х. We have established that it was technologically possible to use electrolytic plasma discharge generated between the electrolytic cathode and the metal anode under pressure of 1×10³–10.1×10t Pa. Based on analysis, we have obtained the dependences for achieving polished surface of products. We have considered calculation of relative machinability coefficient and price for processing depending on complexity coefficients depending on processing time, material, shape and initial parameter Ra of surface roughness, processing accuracy. We have found the costs of consumables, power consumption in repetitive production. We have developed the design of a device for treatment of flange-type products. We have carried out comparative analysis of the costs for manufacturing equipment for jet focused electrolytic plasma treatment. We have formulated rules for protection of product surface and safe operation of personnel during servicing of units of jet focused electrolytic-plasma treatment.
