Description
Summary:The development and implementation of novel galvanic coatings with abnormally high microhardness, wear resistance, and corrosion resistance are the focus of modern machine-building. The galvanic deposition of composite electrolytic coatings (CECs) is an efficient method of improving their properties. In this paper, a chloride-containing electrolyte has been proposed for obtaining a wear-resistant nickel–cobalt–polytetrafluoroethylene CEC. The effect exerted by electrolysis modes and electrolyte compositions on some physicomechanical properties (wear resistance and corrosion resistance) of a nickel–cobalt–polytetrafluoroethylene composite electrolytic coating deposited from chloride-containing electrolyte has been studied. The potentialities of using the deposited layer as wear- and corrosion-resistant coating.
