FIELD: electricity.
SUBSTANCE: method to produce nanomodified galvanic nickel coating includes galvanic deposition of nickel coating, at the same time nanocarbon material is introduced into electrolyte with number of graphen layers of not more than 30, external diametre of fibres from 10 to 60 nm, length of at least 2 mcm and with content of structured carbon of at least 95%, in amount of 0.05-0.08 g/l, afterwards electrolyte with ultrasound. Nanocarbon material may be introduced into electrolyte as uncleaned from nickel catalyst. Recommended mode of ultrasound processing: frequency 22 kHz, amplitude 80 mcm, sound intensity of 786 W/cm2.
EFFECT: achievement of microhardness of nickel coating, exceeding microhardness of chromium-plating.
