NOVELTY - The utility model claims a zinc-nickel alloy plating layer is applied to the zinc-nickel alloy plated layer structure under the corrosion environment, comprising a metal basal body and orderly from inside to outside on the surface of the metal base, and the trivalent chromium passivation layer, hydroxyl graphene modified sealing layer. The metal substrate can be steel substrate or zinc alloy substrate, the hydroxyl graphene modified enclosure layer adopts novel hydroxyl graphene modified sealing agent preparation. The utility model claims a plating layer structure, according to GB/T 10125-1997 "artificial atmosphere corrosion test salt spray test" to neutral salt spray test 600 h, plated surface without generating white corrosion. This plating layer structure has excellent corrosion resistance, lubricity, wear resistance and self-repairing property, and has good market prospect.
