| 摘 要： | 采用水雾化方法制备Fe74Al4Sn2P10C2B4Si4合金粉末，研究发现该合金具有强的非晶形成能力和高热稳定性，在粉末粒度小于400目时可以形成非晶态合金.采用该非晶粉末制备的磁粉芯在高频下品质因数显著高于MPP粉芯，说明该磁粉芯高频损耗较低.分析表明，非晶合金磁粉芯高频下损耗低的主要原因是电阻率较高.

| Abstract: | Fe74Al4Sn2P10C2B4Si4 powder were prepared by water atomization. It has been shown that this alloy has big glass-forming ability (GFA) and high stability against heating. Amorphous alloy powder can be got in size smaller than 400 mesh. Quality factor of the powder core made from this amorphous powder is remarkably higher than that of MPP in high frequency range, which means the core loss of the amorphous powder core is lower than that of MPP. The electrical resistivity of amorphous powder is much higher than that of MPP powder, that is why the amorphous powder core has lower core loss in the high frequency range. |
