摘要
本文应用HDD工艺制备了各向同性的NdFeB磁粉,对磁粉进行了X光衍射分析,并用这种磁粉制备了磁性能为iH_c=896 kA/m, B_r=0.51 T, (BH)_(max)=44 kJ/m^3的各向同性粘结磁体。
The present paper covers the HDD process. The isotropic magnetic powders were prepared by HDD process. We have analysed the magnetic powders by the method of X-ray diffraction. The bonded magnet prepared from the magnetic powders possesses the following properties:iH_c=896kA/m, B_r=0.51T, (BH)_(max)=44kJ/m^3.
