On the Electrochemical Deposition and Properties of Nickel-Based Composite Coatings

Nickel-based composite electrochemical coatings (CECs) modified with graphite nitrate have been obtained. Their microstructure and functional properties (sliding friction coefficient and protective ability) have been studied. It has been found that when a dispersion of graphite nitrate is introduced into a sulfate–chloride electrolyte for nickel plating, the sliding friction coefficient of the formed CECs decreases by half, and the range of potentials of the passive state of these composite coatings increases by 1.26–1.32 times.
