据报道,美爱达荷州爱达荷国家工程环境实验室(INEEL)开发出一种生产钛铁硼(NdFeB)磁性粉末的雾化工艺,能使磁粉比以前生产的磁粉具有更高的高温稳定性。 爱达荷州的GA Powders公司已产业化的雾化工艺主要是把喷射出的熔融合金形成极细的液滴并快速冷却成细小的球状粉末颗粒。以前,该工艺的冷却速率不够快,生产出的粉末颗粒达不到能获得最佳性能的细的显
It has been reported that INEEL, Idaho, USA, has developed an atomization process for the production of NdFeB magnetic powder that enables magnetic powders to have higher temperatures than previously produced magnetic powders stability. GA Powders, Idaho’s industrial atomization process is mainly the formation of very fine droplets of the molten alloy jet and rapid cooling into fine spherical powder particles. Previously, the cooling rate of the process was not fast enough to produce fine particles of powder that did not achieve the best performance
