TITANIUM ELECTRODE MANUFACTURING METHOD Russian patent published in 2013 - IPC C25B11/00 

FIELD: metallurgy.

SUBSTANCE: manufacturing method of titanium electrode (cathode) used for electrolysis of liquid involves pre-treatment of titanium electrode surface in water solution containing 300-350 g/l of hydroxylamine hydrochloride, 40-50 g/l of acid ammonium fluoride during 1-2 minutes at the temperature of 80-90°C, cleaning with hot water and further treatment in water solution of ammonium fluoride 20-25 g/l and 1-1.5 g/l of urotropine during 0.5-1 minute at the temperature of 18-25°C. The above method involves treatment of electrode surface of any shape, including flat, cylindrical, meshed, coaxial and bar ones, etc.

EFFECT: improvement of catalytic activity of electrode surface, which provides low overpressure at the specified current density, is the technical result of the proposed invention.
