    摘要:

    2:17型SmCo永磁材料主要有4種類型的磁體:高溫磁體、超低溫度系數(shù)的磁體、輻射取向和輻射多極取向環(huán)行磁體、高電絕緣磁體。介紹了其制造方法,主要是粉末冶金(燒結(jié))法、還原擴(kuò)散法和快淬-粘結(jié)法;描述了磁體的胞狀顯微組織結(jié)構(gòu)和成分對(duì)結(jié)構(gòu)的影響:總結(jié)了其矯頑力機(jī)理,特別是高溫下的矯頑力機(jī)制;并對(duì)該永磁材料的今后研究趨勢(shì)作了評(píng)述。

    Abstract:

    Research and development of 2:17 type SmCo permanent magnets are reviewed. Considered are four magnets types : high temperature magnets, super-low temperature coefficient magnets, the radially oriented and multi-polar rings, high electricity insulation magnets. Manufacturing techniques described include: powder metallurgy (sintering), reverting-diffuse and quenching-bonding. The cellular microstructure was characterized, and the effects of components on microstructure were discussed. The coercivity mechanism over a wide temperature range was considered and directions for future research discussed.
