On the Electrodeposition of Zinc-Based Composition Coatings in the Pulse Mode

Аннотация

Zinc-based composition electrochemical coatings (CECs) modified with carbon nanotubes (CNTs) have been fabricated in the pulse mode of electrolysis. Their microstructure and functional properties (sliding friction coefficient and protective ability) have been studied. It has been determined that the sliding friction coefficient of the CECs decreases by 1.32–1.43 times with the introduction of the CNT dispersion into ammonium sulfate zinc solution, while the passivity range of these coatings increases by a factor of 1.35–1.39.
