FIELD: chemistry.
SUBSTANCE: method involves preparation of a suspension of nanodiamond powder and a liquid phase, adding the suspension to an electrolyte and conducting electrolysis to deposit a composite coating. The liquid phase used to prepare the suspension is ethyl alcohol or acetone, wherein the nanodiamond powder is added to the liquid phase in amount of 60-80 vol. %, and the powder in the suspension is dispersed by crushing and attrition grinding with a lap, after which the suspension is added to the electrolyte.
EFFECT: dispersing nanodiamond powder and endowing the powder with resistance to sedimentation and coagulation in the electrolyte.
