摘要
稀土永磁材料性能优异,应用前景广阔。高丰度稀土(La、Ce、Y等)永磁材料的开发与利用有利于平衡稀土资源的利用,弥补目前市面上磁能积36~200 kJ/m^(3)之间性能的磁体使用。针对未来智能制造对更高性能永磁材料的期待,晶界扩散技术是目前制备高特性磁体的重要手段,如何进一步提升磁体扩散深度以及与现有工艺结合,是晶界扩散技术发展需要解决的首要问题。对于新一代永磁材料的探索从未停止,从理论研究变为现实生产,还有一段发展历程需要经历。
Rare earth permanent magnetic materials have excellent properties and broad application prospects.The development and utilization of high abundance rare earth(La,Ce,Y,etc.)permanent magnetic materials is conducive to balance the utilization of rare earth resources and making up for the use of magnets with magnetic energy product of 36~200 kJ/m^(3)on the market.In view of the expectation of future intelligent manufacturing for higher performance permanent magnet materials,grain boundary diffusion technology is an important means to prepare high-performance magnets at present.How to further improve the diffusion depth of magnets and combine with existing processes is the primary problem to be solved in the development of grain boundary diffusion technology.The exploration of a new generation for permanent magnetic materials has never stopped,there is still a period of development to go through from theoretical research to practical production.
