SYNTHESIS AND ELECTROCHEMICAL PROPERTIES OF COMPOSITE GALVANIC Ni WITH CARBON NANOMATERIALS AND PVD Mo COATINGS

Abstract

Double layer coatings Ni – Mo were obtained by electrolytic deposition of galvanic Ni and following arc PVD deposition of molibdenium. The ion plating coatings Mo on Ni foil and composition electrolytic Ni coatings with carbon nanomaterials (CNM) deposited on mild steel has been also investigated. Composite galvanic Ni coatings with CNM and ion plating coatings Mо contain separately obtained cubic α-Мо phase as well as fragmentary solid solution Мо in Ni. Such coatings exclude hydrogenation of Ni foundation in alkaline solution and possess enlarged electrocatalytic properties while emitting hydrogen and oxidgen. Availability of carbon based nanomaterials in combined coatings is cause of an active absorbtion hydrogen after cathodic polarization. A formation on the surface layer of nanostructure solid solution (Ni, Mo) after compression plasma flows treatment with fixed parameters of patterns Mo/Ni/ mild steel take place.
