摘要

本文介绍了高温钐钴磁体在PPM配置中的热稳定性和性能数据的新结果。根据几年的实验和观察，这些高温磁铁在高达550/spl度/C的温度下具有冶金稳定性。在初始热稳定两小时后，这些无涂层磁铁在空气中保持300/spl度/C超过三年，损耗仅为0.3%。

Thermal stability and performance data for Sm-Co 2:17 high temperature magnets on PPM focusing structures

This paper covers new results on the subjects of thermal stability and performance data for high temperature Sm-Co magnets in PPM configurations. Based on several years of experiments and observations, these high temperature magnets are metallurgically stable at temperatures up to 550/spl deg/C. Following initial thermal stabilization for two hours, these uncoated magnets, held at 300/spl deg/C in air for more than three years, had losses of only 0.3%.
