Abstract

Composite electrochemical coatings based on nickel with colloidal graphite and graphite bisulphate as a disperse phase are obtained. The electrodeposition of the coatings in a variable potential mode is studied. It is determined that the coefficient of sliding friction for the developed coatings decreases by a factor of two in comparison with nickel coatings without the dispersed phase. It is shown that the coefficient of friction for the coatings decreases as the thickness of the electrolytic deposit rises.
