FIELD: metallurgy.
SUBSTANCE: method of fabrication of electrode for electrolysis of water solutions of alkali metal chlorides consists in preliminary treatment of electrode titanium base surface, in application coating onto it, where coating consists of thermo-decomposed compounds of titanium, iridium and ruthenium; further the method consists in their succeeding thermal treatment in oxidising atmosphere and in producing electro-catalytic coating containing oxides of titanium, iridium and ruthenium; also surface of electro-catalytic coating is additionally treated with 20-25% water solution of hydrogen peroxide by means of sputtering it at amount of 80-140 g/m2 and successively heat treated at temperature of 450-480°C.
EFFECT: raised resistance of electrode, increased service life.
