NOVELTY - The utility model claims a plating layer structure for plating bronze and nano graphene, comprising a metal base body and a cyanide pre-plating copper layer from inside to outside in turn on the metal substrate, a middle copper plating layer, a bright copper plating layer, a bronze plating layer, a gun black tin nickel alloy plating layer and a graphene sealing layer. model claims a copper plating layer structure, using aqueous graphene sealing agent to replace the traditional solvent type transparent paint, no pollution to the production environment, and good corrosion resistance. according to GB/T 10125-2012 artificial atmosphere corrosion test salt mist test for neutral salt fog test for 48 h, plating surface without corrosion, the corrosion resistance is higher than the traditional solvent transparent paint closed copper layer.
