The purpose of these studies is to compare the parameters of the galvanic process using a conventional method for electrodeposition of ZnNi coating with a new method using a membrane system. The study was conducted on a pilot production barrel line using electrolytes operating in industrial conditions. The coating was applied to M6 carbon steel bolts mass-produced and heat-treated. The composition of both baths and their cathode current efficiency was analyzed. The deposition rate and concentration of nickel in the coating were evaluated. Studies have shown a difference in coating deposition rates and in the content of nickel in the coating.Keywords: Fasteners, alloy coatings, current efficiency, membrane system
