▎ 摘  要

NOVELTY - The utility model claims a protective layer structure of neodymium-iron-boron coating graphene comprising a neodymium-iron-boron base body, and a citrate pre-plating nickel layer and graphene electrophoresis paint coating layer prepared from inside to outside sequentially the neodymium-iron-boron base body. The protective layer structure prepared by the utility model, according to GB/T 10125-2021 " artificial atmosphere corrosion test salt fog test " for neutral salt fog test 480h plating surface without corrosion. The protective layer structure preparation technique is environment-friendly, and has good corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the protective layer structure of neodymium-iron-boron coating graphene to claim.
