NOVELTY - The utility model claims a neodymium-iron-boron zinc-plated nickel alloy and graphene structure of the sealing, comprising a neodymium-iron-boron substrate, and citrate pre-plating nickel layer prepared from inside to outside sequentially the neodymium-iron-boron substrate, pyrophosphate copper plating layer, zinc-nickel alloy plating layer, trivalent chromium blue passivation layer, and a graphene sealing layer. The utility model claims a neodymium-iron-boron zinc-plated nickel alloy and graphene structure of the sealing, according to GB/T 10125-2012 " artificial atmosphere corrosion test salt fog test " for neutral salt spray test 1000h after plating the surface without white corrosion. The plating layer structure has good corrosion resistance.
