FIELD: metallurgy.
SUBSTANCE: coating of nano-crystal oxide tungsten bronzes is produced by electrolysis of poly-tungstate melt with utilisation of platinum cathode and anode. Electrolysis is carried out under pulse controlled potential mode at over-voltage 200-300 mV in melt containing mol %: K2WO4 - 30, Li2WO4 - 25 and WO3 - 45, also, as cathode there is used platinum foil with texture (110).
EFFECT: nano-crystal coating in form of foils of nano-metre thickness.
