Electrochemical Deposition and Properties of Nickel—Chromium–Graphene Oxide Composite Coatings

Abstract—Composite electrochemical coatings (CECs) based on nickel–chromium alloy modified with multilayer graphene oxide (GO) have been obtained. The kinetics of the process of electrodeposition of these coatings in potentiodynamic and galvanostatic modes has been studied. The structure and composition of nickel–chromium–GO CECs were investigated by scanning electron microscopy and laser microspectral analysis. It was found that the inclusion of GO particles in the composition of electrolytic deposits of nickel–chromium alloy increases their microhardness.
