▎ 摘  要

NOVELTY - A composite electroplating solution contains 0.05-0.3 g graphene oxide, 35-40 g zinc chloride, 160-165 g ammonium chloride, 10-16 g hexamethylenetetramine, 10-15 g trisodium citrate, 0.8 g composite additive and balance amount of distilled water. The composite additive contains saccharin, benzalacetone and Peregal (RTM: nonionic surfactant) in a mass ratio of 1:2:15. USE - Composite electroplating solution is useful for forming zinc-graphene oxide composite coating for surface of steel workpiece (claimed). ADVANTAGE - The composite electroplating solution has excellent dispersibility and corrosion resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of composite electroplating solution, which involves weighing raw materials and then uniformly mixing, stirring the mixture and then adjusting pH value to 4.5-5 using hydrochloric acid solution, and ultrasonically processing; and (2) use of composite electroplating solution for forming zinc-graphene oxide composite coating for surface of steel workpiece.
