Abstract：In this study, the surface modification treatment of FeSiCr alloy powder was carried out with zinc-man‐
ganese 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 mag‐
netization 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, 50 mT).
