NOVELTY - The utility model claims a rolling plating shallow black nickel and nano graphene sealed plating layer structure, comprising a metal substrate, a pre-plating copper layer, a nickel plating layer, a gun black plating layer and a nano graphene sealing layer prepared from inside to outside on the metal substrate. The shallow black nickel plating layer structure provided by the utility model is sealed by hydroxyl graphene sealing agent; the plating layer has good corrosion resistance, which overcomes the technical defect of bad corrosion resistance of the traditional rolling plating shallow black nickel plating layer; it has good market prospect.
