    摘要
  • 摘要: 研究了HDDR三元NdFeB各向異性磁粉的制備工藝.發現脫氫速度對HDDR三元各向異性NdFeB的磁性能具有顯著影響;緩慢的脫氫處理有助于材料獲得高的各向異性.在最佳工藝條件下,可獲得磁能積為84 kJ·m3的HDDR三元NdFeB各向異性粘結磁體.

     

    Abstract: The preparation process of HDDR ternary NdFeB anisotropic powder was studied. The research results showed that the effects of desorption rate of hydrogen on the magnetic properties of HDDR ternary NdFeB anisotropy were remarkable, and slow desorption treatment was beneficial to the attainment of strong anisotropy. By the optimum HDDR treatment, the HDDR ternary NdFeB anisotropy bonded magnet with Br of 0.78 T,iHc of 640 kA·m-1 and (BH)max of 84kJ·m-3 can be obtained.
