摘要:Jet electrodeposition is an effective method to prepare protective coatings on NdFeB. To improve the performance of interlaced multilayer coatings, layers that changed periodically and gradiently were prepared by changing the current density for even layers. The surface morphology and microstructure of the coatings were characterized by scanning electron microscopy and X-ray diffraction. The adhesion strength, microhardness, and corrosion resistance of the coatings were measured using an automatic scratch tester, a microhardness tester, and an electrochemical workstation. The results indicated that compared with other coatings, the periodic gradient multilayer coatings obtained a flatter surface and a higher corrosion resistance. In addition, the adhesion strength was increased from 9.2N to 21.7N, and the microhardness was increased from 484HV to 539HV.
