FIELD: technical electrochemistry.
SUBSTANCE: invention can be used in chemical engineering, electronics and automotive industries, and heat engineering. The method involves deposition of a hybrid coating on steel grade 08kp at a voltage of 15 V from an aqueous electrolyte solution containing nickel sulphate, citric acid, salts of molybdenum, cobalt, iron, boric and polyacrylic acids, with a ratio of average cathode and anodic currents over the period of 1.1 :1-1.4:1; pH 4-5, temperature 65°C at the following ratio of components (g⋅l -1):
EFFECT: increasing the emissivity (degree of emissivity) of the resulting coatings.
