Abstract Novel amorphous magnetic-compound powder cores (AMPCs) composed of a mixture of water-atomized FeSiBPNbCr amorphous powder and FeCo alloy powder were successfully fabricated through cold pressing. FeCo alloy powder, which exhibits a high magnetic flux density (Bs) of 2.35 T, can improve the Bs and DC bias performance of the AMPCs. Compared to raw amorphous powder cores, the Bs and DC bias performance of AMPCs containing 30% FeCo alloy powder were improved by 35% and 24%, respectively. The core loss (Pcv) was maintained lower than 1000 mW/cm3, at a maximum magnetic induction of 0.1 T and frequency of 100 kHz. Novel AMPCs with high Bs, low Pcv, and good DC bias performance meet the needs of the new high-frequency large-current devices and have wide application prospects.

添加FeCo合金粉增强直流偏置性能的新型Fe基非晶复合粉芯

摘要 通过冷压成功制备了由水雾化FeSiBPNbCr非晶粉末和FeCo合金粉末混合而成的新型非晶磁性复合粉芯(AMPCs)。FeCo 合金粉末具有 2.35 T 的高磁通密度 (Bs)，可以提高 AMPC 的 Bs 和直流偏置性能。与原始非晶压粉磁芯相比，含有 30% FeCo 合金粉末的 AMPC 的 Bs 和 DC 偏置性能分别提高了 35% 和 24%。磁芯损耗 (Pcv) 保持在 1000 mW/cm3 以下，最大磁感应强度为 0.1 T，频率为 100 kHz。具有高Bs、低Pcv和良好直流偏置性能的新型AMPCs满足了新型高频大电流器件的需求，具有广阔的应用前景。
