摘　　要：采用锌锰磷化液对FeSiCr合金粉末进行表面改性处理,通过振动样品磁强计、阻抗分析仪和软磁材料交流测试装置分析锌锰磷化液浓度对FeSiCr磁粉饱和磁化强度、FeSiCr磁粉芯有效磁导率和功率损耗的影响。结果表明,随着锌锰磷化液浓度的增加,样品的饱和磁化强度逐渐减小,功率损耗先减小后增大。当锌锰磷化液浓度为25%时,有效磁导率为39.5,功率损耗仅为103.6 W·kg^(-1)(100 kHz,50 mT)。In this study,the surface modification treatment of FeSiCr alloy powder was carried out with zinc-manganese phosphating solution.Vibrating sample magnetometer,impedance analyzer and soft magnetic material AC test device were used to analyze effects of the content of zinc-manganese phosphating solution on saturation magnetization of FeSiCr magnetic powder,effective permeability and power loss of FeSiCr magnetic powder cores.The results show that with the increase of the concentration of zinc-manganese phosphating solution,the saturation magnetization of the composite magnetic powder core gradually decreases,the power loss first decreases and then increases.When the concentration of zinc-manganese phosphating solution is 25%,the effective permeability is 39.5,and the power loss is only 103.6 W·kg^(-1)(100 kHz,50mT).
