Effect of ($ TbF_{3} $ + $ CaH_{2} $) pastes grain boundary diffusion on coercivity and remanence of GaAlCu-doped Nd–Fe–B sintered magnets
Abstract Grain boundary diffusion of $ TbF_{3} $ can improve the magnetic properties and thermal stability of NdFeB sintered magnets. The reducing agent $ CaH_{2} $ can effectively release reducing gas at high temperature, improve the atmosphere in the furnace. In this paper, the diffusion behavior...

| 520 | |a Abstract Grain boundary diffusion of $ TbF_{3} $ can improve the magnetic properties and thermal stability of NdFeB sintered magnets. The reducing agent $ CaH_{2} $ can effectively release reducing gas at high temperature, improve the atmosphere in the furnace. In this paper, the diffusion behavior and coercivity enhancement by printing ($ TbF_{3} $ + $ CaH_{2} $) pastes on the sintered NdFeB magnets was investigated. After diffusion, the coercivity increased rapidly from 15.7 to 28.4 kOe. Tb atoms diffuse first to the surface and then to the interior of the magnet, forming a network of Tb-rich shells around the $ Nd_{2} $$ Fe_{14} $B grains. The higher magnetic crystal anisotropy (Nd,Tb)2$ Fe_{14} $B phase determines the coercivity enhancement. This analysis was confirmed by FE-SEM and EDS observations of the microstructure and element distribution of the magnet. In addition, the effect of grain boundary diffusion on the remanence and thermal stability of the magnet was also studied. The results of this study have certain guiding significance for the preparation of sintered NdFeB magnets with high coercivity by diffusion technology. | ||

The reducing agent $ CaH_{2} $ can effectively release reducing gas at high temperature, improve the atmosphere in the furnace. In this paper, the diffusion behavior and coercivity enhancement by printing ($ TbF_{3} $ + $ CaH_{2} $) pastes on the sintered NdFeB magnets was investigated. After diffusion, the coercivity increased rapidly from 15.7 to 28.4 kOe. Tb atoms diffuse first to the surface and then to the interior of the magnet, forming a network of Tb-rich shells around the $ Nd_{2} $$ Fe_{14} $B grains. The higher magnetic crystal anisotropy (Nd,Tb)2$ Fe_{14} $B phase determines the coercivity enhancement. This analysis was confirmed by FE-SEM and EDS observations of the microstructure and element distribution of the magnet. In addition, the effect of grain boundary diffusion on the remanence and thermal stability of the magnet was also studied. The results of this study have certain guiding significance for the preparation of sintered NdFeB magnets with high coercivity by diffusion technology.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">NdFeB sintered magnet</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TbF</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Microstructure</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Grain boundary diffusion</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CaH</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Magnetic properties</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Huang, Weichao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Dan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Qilin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Luo, Liang</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhou, Xiang</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied physics.

Effect of ($ TbF_{3} $ + $ CaH_{2} $) pastes grain boundary diffusion on coercivity and remanence of GaAlCu-doped Nd–Fe–B sintered magnets |
| abstract |
Abstract Grain boundary diffusion of $ TbF_{3} $ can improve the magnetic properties and thermal stability of NdFeB sintered magnets. The reducing agent $ CaH_{2} $ can effectively release reducing gas at high temperature, improve the atmosphere in the furnace. In this paper, the diffusion behavior and coercivity enhancement by printing ($ TbF_{3} $ + $ CaH_{2} $) pastes on the sintered NdFeB magnets was investigated. After diffusion, the coercivity increased rapidly from 15.7 to 28.4 kOe. Tb atoms diffuse first to the surface and then to the interior of the magnet, forming a network of Tb-rich shells around the $ Nd_{2} $$ Fe_{14} $B grains. The higher magnetic crystal anisotropy (Nd,Tb)2$ Fe_{14} $B phase determines the coercivity enhancement. This analysis was confirmed by FE-SEM and EDS observations of the microstructure and element distribution of the magnet. In addition, the effect of grain boundary diffusion on the remanence and thermal stability of the magnet was also studied. The results of this study have certain guiding significance for the preparation of sintered NdFeB magnets with high coercivity by diffusion technology. © The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature 2022.
