摘要：Sintered neodymium (NdFeB) magnet material is highly vulnerable to corrosion. To solve this problem, three kinds of structures (dark nickel, bright nickel, and multilayered nickel) were produced efficiently and quickly by using jet electrodeposition technology. The structure and microstructure of the coatings were analysed by X-ray diffraction and field-emission scanning electron microscopy, respectively. The corrosion resistance of the samples was evaluated by potentiodynamic polarisation (Tafel). By comparing the corrosion behaviours of different structures, we found that the corrosion resistance of multilayered structure nickel coating was much higher than that of single layered nickel and the surface quality was significantly improved compared with dark nickel, which can better protect the NdFeB material.
