The optimal carbon concentration providing high-quality coatings with improved properties was established. The process of stability of suspensions (containing carbon material obtained from the shell of hazelnuts) in time in water, aqueous solutions of surfactants, and in a nickel-plating electrolyte after dispersion has been investigated. It was found that dispersing has a positive effect on the stability of aqueous suspensions. The addition of an ionic surfactant does not affect the stability of the suspension. Non-ionic surfactants increase the stability of the medium and electrolyte solutions sharply reduce the stability. The wear resistance of carbon-containing composite coatings was investigated. The wear of the CEC copper-carbon material depends on the concentration of carbon material inclusions in the matrix. The maximum wear resistance is achieved at a concentration of the second phase in a suspension of 0.04 g/L, with a carbon content in composite coatings of 6.53-8.06% (mass). It is established that the wear of the CEC is 1.5 times less than the wear of “clean” copper coating.encarbonsecondary raw materialsdispersionsuspensionნახშირბადიმეორადი ნედლეულიდისპერსიასუსპენზიაjournal-article10.24214/IJGHC/GC/10/1/05359
