Publication number: 20240116106Abstract: The present disclosure relates to the technical field of neodymium-iron-boron preparation, in particular to a method for improving the coercivity of a neodymium-iron-boron magnet and a magnet prepared by the method. The method specifically includes: (S1) subjecting a heavy rare earth diffusion source powder, an organic adhesive, a spherical high temperature resistant ceramic powder and an organic solvent to mixing and stirring to prepare a heavy rare earth slurry; (S2) coating a surface of a neodymium-iron-boron magnet with the heavy rare earth slurry and drying the heavy rare earth slurry to form a heavy rare earth coating; and (S3) performing high-temperature diffusion and aging treatment. According to the method above, the heavy rare earth coating has high hardness and strength. In addition, the neodymium-iron-boron magnet has higher and more uniform properties after diffusion, and less heavy rare earth elements are consumed.Type: ApplicationFiled: October 9, 2023Publication date: April 11, 2024Inventors: Kunkun YANG, Zhongjie PENG, Chuanshen WANG, Kaihong DING
