Study of Electrodeposition and Functional Properties of Nickel-Graphite Bisulfate Composite Coatings

Resumo

Nickel-based composite electrochemical coatings modified with graphite bisulfate were obtained. The functional properties (sliding friction coefficient, protective capacity) of these coatings as compared with nickel coatings without a dispersed phase were examined. It was found that, when graphite bisulfate particles are incorporated in nickel deposits, the coefficient of sliding friction becomes 2.30–2.40 smaller and the range of passive-state potentials increases by a factor of 1.32–1.40.
