FIELD: chemistry.
SUBSTANCE: method includes electrodeposition of a layer of La and 3d metals Mn, Co, Cu, Ni from the solution of chlorides of metals used in the protophilic protonic organic solvent, the electrochemical decomposition potential of which is moderately higher than the electrochemical potential of the discharge of metal cations in the medium of the corresponding solvent, the electrodeposition of the metal layer are carried out in a background electrolyte medium, while the heat treatment of the coated surface is carried out at a temperature of 950-1100°C in the air.
EFFECT: invention makes it possible to obtain a protective coating of the interconnector surface, effective both in the oxidizing and reducing atmosphere for the protected chromium steel of various compositions.
