FIELD: metallurgy.
SUBSTANCE: proposed method comprises making nanoparticles of graphene, preparing ionised suspension with graphene nanoparticles, introducing said suspension to flask with electrodes to precipitate graphene nanoparticles at direct current so that graphene coating is produced at articles connected to current source negative pole. Note here that said suspension features hydrogen ion exponent of 5-12 pH while said coating is made by direct current with density of 25 mA/cm2 and voltage of 80-110 V.
EFFECT: higher quality of coatings applied on various material.
