Electrochemical Deposition of Composite Nickel-Graphene Oxide Coatings in the Reverse Mode

摘要

Nickel-based composite electrochemical coatings (CECs) modified with multilayer graphene oxide (GO) from a sulfate-chloride electrolyte in a reverse electrolysis mode have been obtained. The structure of the CEC data was studied by scanning electron microscopy. The corrosion-electrochemical behavior of nickel-GO composite coatings in a 0.5 M solution of H2SO4 was investigated. It has been established that, when GO particles are included in the composition of electrolytic nickel deposits, their protective ability to corrosion increases by a factor of 1.40.
