摘要： 研究了不同磁场退火和浸漆固化工艺对Fe₈₂Si_3.8B_13.9C_0.3非晶合金环形铁芯损耗和磁性能的影响,并与1K101合金铁芯进行了对比。结果表明:与1K101合金相比,Fe₈₂Si_3.8B_13.9C_0.3合金铁芯的最佳退火温度低于1K101合金,其中纵磁退火时达到最低,为330 ℃。纵磁退火Fe₈₂Si_3.8B_13.9C_0.3合金铁芯有着更高的饱和磁感应强度,B_{3500 A/m}=1.611 T。经350 ℃无磁场退火处理后,Fe₈₂Si_3.8B_13.9C_0.3合金铁芯的损耗P_{50 Hz, 1.4 T}=0.360 W/kg,稍高于1K101合金;经330 ℃纵磁退火处理后,Fe₈₂Si_3.8B_13.9C_0.3合金铁芯的损耗P_{50 Hz, 1.4 T}=0.257 W/kg,也高于1K101合金;经350 ℃横磁退火处理后损耗P_{50 Hz, 1.4 T}=0.163 W/kg,低于1K101合金。纵磁退火Fe₈₂Si_3.8B_13.9C_0.3合金铁芯经浸漆固化处理后,磁通密度B_{800 A/m}=1.341 T,比纵磁退火1K101合金浸漆固化铁芯高15%;纵磁退火且浸漆的Fe₈₂Si_3.8B_13.9C_0.3合金铁芯损耗低于1K101合金浸漆铁芯,且随着频率升高优势更加明显;当频率大于1000 Hz时,纵磁退火且浸漆的Fe₈₂Si_3.8B_13.₉C_0.3合金铁芯的损耗值低于未浸漆铁芯。

Abstract: Effects of different annealing and dipping paint curing processes on the loss and magnetic properties of the Fe₈₂Si_3.8B_13.9C_0.3 amorphous alloy toroidal core were studied and compared with 1K101 alloy core. The results indicate that the optimum annealing temperature of the Fe₈₂Si_3.8B_13.9C_0.3 alloy core is lower than that of 1K101 alloy, and the lowest temperature is 330 ℃ in longitudinal magnetic annealing. Longitudinal annealed Fe₈₂Si_3.8B_13.9C_0.3 alloy core has higher saturation magnetic induction, B_{3500 A/m}=1.611 T. After annealing at 350 ℃ without magnetic field, the loss of the longitudinal annealed Fe₈₂Si_3.8B_13.9C_0.3 alloy is slightly higher than that of 1K101 alloy, P_{50 Hz, 1.4 T}=0.360 W/kg. After longitudinal magnetic annealing at 330 ℃, the loss is also higher than that of the 1K101 alloy, P_{50 Hz, 1.4 T}=0.257 W/kg. After transverse magnetic annealing at 350 ℃, the loss is lower than 1K101 alloy, P_{50 Hz, 1.4 T}=0.163 W/kg. After cured by dipping, the magnetic flux density of the Fe₈₂Si_3.8B_13.9C_0.3 alloy core is 15% higher than that of the 1K101 alloy and B_{800 A/m}=1.341 T. The core loss of the Fe₈₂Si_3.8B_13.9C_0.3 alloy is lower than that of the 1K101 alloy after longitudinal magnetic annealing and dipping paint curing, and the advantage is more obvious with the increase of frequency. When the frequency is higher than 1000 Hz, the loss value of longitudinal magnetic annealed and cured Fe₈₂Si_3.8B_13.9C_0.3 alloy core is lower than that of the uncured core.
