摘要:
Sm2Co17基永磁材料具有高的居里温度,优越的综合磁性能和良好的环境稳定性,在新型战机、无人机、雷达系统、军事卫星、空间探索等方面有重要应用，西方各发达国家将Sm2Co17基永磁材料列为材料领域重点研究对象之一。我国早在上世纪七十年代就开展钐钴永磁材料的研制，至今已有近四十年的历史。Sm2Co17基永磁材料经过多年的发展，陆续形成高磁能积、低剩磁温度系数和高使用温度三大系列材料，国内外在这些方面已做了大量的研究工作。本文从高性能、低温度系数和高使用温度钐钴永磁材料方面梳理了钐钴永磁材料的研究进展，总结了钐钴永磁材料的微结构和矫顽力的研究现状，并对Sm2Co17基永磁材料的发展方向提出展望。
Abstract:
Due to the high Curie temperature, superior magnetic properties and good environmental stability, Sm2Co17-based permanent magnet materials have been widely used in novel aircraft, drones, radar systems, military satellites, and space exploration applications. Western developed countries list Sm2Co17-based permanent magnet materials as one of the most important materials which should be researched. The development of samarium cobalt permanent magnetic materials has been nearly 40 years, and Sm2Co17-based permanent magnets have been developed as high maximum-energy-product, low remanence- temperature-coefficient and high-temperature materials for three series. In this paper, based on the high performance, low temperature coefficient and high temperature application, the researches and developments of samarium cobalt permanent magnetic materials were summarized, and coercivity mechanism of Sm2Co17- based permanent magnetic materials was discussed. Finally, the development prospects of this type of permanent magnets were presented.
