FIELD: metallurgy.SUBSTANCE: invention relates to electrochemical processing of work pieces from non-ferrous metals, namely to the water solution of electrolyte used for processing. The electrolyte solution contains lemon acid with the concentration within a range from 1.665 g/l up to 982 g/l, ammonium bifluoride with the concentration from 2 g/l up to 360 g/l and no more than 3.35 g/l of strong acid. The work piece surface treatment includes exposure of the surface to influence of a bathtub with water solution of electrolyte, regulation of temperature of a bathtub is less or equal 85°C, connection of the work piece to the anode of DC power supply and immersion of the cathode of DC power supply into the bathtub and passing through the bathtub of the current less than 255000 amperes per square meter.EFFECT: invention allows to use the electrolyte water solution for processing of various non-ferrous metals, meanwhile the electrolyte is environmentally safe and doesn't generate hazardous wastes.29 cl, 12 dwg, 9 tbl |
