FIELD: chemistry.
SUBSTANCE: method includes polishing component of copper-containing alloy in electrolyte, used as anode, and synchronous application of copper coating on steel component, used as cathode. Voltage 250-340 V is supplied to cathode and anode with electrolyte temperature 60-90°C. Electrolyte is used in form of water solution, which contains ammonium chloride, ammonium fluoride and mono-, di-, tri-substituted ammonium citrate or their mixture.
EFFECT: polishing of active anode to mirror lustre with synchronous covering of steel cathode surface with copper.
