Abstract <p>A method for calculating the scattering capacity using a sectional anode for the electrolytic-plasma polishing variant, both with and without taking into account the edge effects, has been developed and tested. An increase in the scattering capacity of the electrolyte is shown to depend on both an increase in the hydrodynamic parameters of the sulfate electrolyte and a decrease in the processing voltage, in the electrolyte temperature, and in the concentration of ammonium sulfate in the electrolyte. The maximum scattering capacity (taking into account the edge effects) was found to be 95% at a processing voltage of 250 V, an electrolyte temperature of 60°С, and an ammonium sulfate concentration of 3%.</p>
