FIELD: chemistry.
SUBSTANCE: method includes degreasing titanium, washing it in running water, activating in an acid solution, platinizing in electrolyte containing cis-diamminedinitroplatinum and sulfuric or sulfamic acid, heat treating platinized titanium in an inert atmosphere at a temperature of 500°C, wherein before degreasing titanium is subjected to sandblasting, the activation of titanium is carried out in the solution of hydrofluoboric acid, and the electrolyte is further added to pyridine-3-sulfonic acid, and electrolysis is carried out at reversing current with the periodic change of polarity of the anode and cathode.
EFFECT: producing high-quality galvanic coatings made of platinum with a thickness of more than 2 mcm.
