Antioxidation effects on the powders and sintered magnets of Sm(Co, Cu, Fe, Zr)z treated by of different methods were studied by TGA and DTA. Microstructure of Sm(Co, Cu, Fe, Zr)z sintered magnets was analyzed through SEM and EDS.

• 通过热重和差热实验研究了不同抗氧化工艺对Sm(Co,Cu,Fe,Zr)z合金粉末抗氧化效果和永磁体性能的影响,采用SEM,EDS对磁体显微组织的变化进行分析。
