FIELD: chemistry.
SUBSTANCE: method involves electrochemical oxidation in a sulphate electrolyte containing detonation nanodiamonds, using detonation nanodiamonds modified with ammonia, antimony or boron in the amount of 0.5-10.0 g/l.
EFFECT: increasing the microhardness and corrosion resistance of coating, reducing its porosity at low flow rate of DNA by simple technology.
