Development of High Performance Dry-Press Anisotropic Permanent Magnet Ferrites 高性能各向异性干压永磁铁氧体的研制
The magnetic powder for dry-pressed anisotropic permanent magnetic strontium ferrite was treated by premagnetization, mechanical dispersion together with the addition of melted polymer, and the effect of ferrite particle state on the properties of magnet was studied. 采用预磁化、机械分散和熔融聚合物黏合剂处理铁氧体磁粉,研究了粉体颗粒状态对干压各向异性锶铁氧体磁性能的影响。
The HDDR ( hydrogenation-disproportionation-desorption-recombination) process was a special method to produce anisotropic Nd_2Fe_ ( 14) B-based magnet powder. HDDR(氢化歧化脱氢重组)工艺是一种用于生产各向异性Nd2Fe14B基磁粉的特殊方法。
This paper also discusses production principle and present state of anisotropic Nd-Fe-B magnetism powder, and the applications and potential market of Nd-Fe-B magnet made by injection molding are also explored. 同时还论述了各向异性Nd-Fe-B磁粉的生产原理及生产现状。指出了注射成形Nd-Fe-B粘结磁体的现在和潜在的应用市场。
