摘　　要：用宽为20 mm、厚为25μm的Fe73.5Cu1Nb3Si13.5B9非晶带材绕制成环型磁芯,将其经550℃×100 min晶化退火处理制成纳米晶磁芯,研究环氧树脂封装对纳米晶磁芯软磁性能的影响。结果表明:与环氧树脂封装前相比,起始磁导率μ0、最大磁导率μm、幅值磁导率μa、饱和磁感应强度Bs、直流损耗Pu和交流损耗Ps减小,矫顽力Hc增大;当测试频率不变时,电感Ls和品质因数Q减小。Annular magnetic cores were wound with amorphous strips Fe73.5Cu1Nb3Si13.5B9 with 20 mm width and 25 μm thickness,and sintered at 550 ℃ for 100 min,and so,the Fe73.5Cu1Nb3Si13.5B9 nanocrystalline magnetic cores were prepared. The influence of epoxy resin packaging on the soft magnetic property was studied. The experiment results show that the initial magnetic permeability（μ0）,the maximum magnetic permeability（μm）,the amplitude magnetic permeability（μa）,the saturation magnetization（Bs）,the DC loss（Pu）and the AC loss（Ps）decrease,and the coercivity（Hc）increases after packaging with epoxy resin. The inductance（Ls）and quality factor（Q）decrease under the same test frequency.
