| Abstract Scope |
Carbon film, one kind of carbon material, is a promising candidate for the protective films or coatings on the metal surfaces due to its unique chemical and physical properties. The electrochemical reduction of carbonate in molten salt is considered as a promising method for carbon materials preparation. In this study, Ni and Mo were selected as electrodes to investigate the reduction process of carbonate on their respective electrode surfaces, and to explore how to prepare uniform and dense carbon film in molten LiCl. The influences of electrolysis conditions such as substrate material, current density and electrolysis method were investigated. The formation of a dense and uniform carbon layer on Ni was difficult as nickel carbide was hard to form. On the contrary, electrochemical reduction of carbon on molybdenum substrate is easy account for the molybdenum carbide formation. |
