由于粘结Nd-Fe-B永磁体具有净成型、自动化生产等优点,其商业价值备受关注。介绍了NNd-Fe-B磁粉的制备方法、粘结Nd—Fe-B永磁体的制备工艺以压常用的粘结剂、添加剂的类型,提出了粘结Nd—Fe-B永磁材料具有广阔的应用前景。
As the bonded Nd-Fe-B permanent magnets have the advantages of near net shape and automated production and so on,their commercial value is concerned greatly. In this paper, the method of fabrication of Nd-Fe-B magnetic powder, the process of fabrication of bonded Nd-Fe-B permanent magnets, and the binder and additive types are introduced. It is considered that the bonded Nd-Fe-B permanent magnets can be used in a wide range of applications in the future.
