Electrochemical Deposition of Zinc-Based Composite Coatings Modified with Carbon Nanotubes from Alkaline Electrolyte

摘要

Composite electrochemical coatings (CECs) based on zinc, modified with carbon nanotubes (CNTs) from an alkaline electrolyte in a pulsed electrolysis mode have been obtained. The microstructure and tribological properties of these CECs are investigated. It was found that the introduction of the dispersed CNT phase into the alkaline galvanizing electrolyte reduces the sliding friction coefficient of the forming coatings by a factor of 1.30-1.45. The corrosion-electrochemical behavior of zinc-CNT CECs in 0.5 M solution of H2SO4 has been described.
