Microstructure And Magnetic Properties

An iron-based soft magnetic composite with Fe3O4-MnZnFe2O4 insulation coating has been prepared by powder metallurgy method. This work investigated the microstructure and magnetic properties of Fe/Fe3O4-MnZnFe2O4 powder cores. Scanning electron microscopy (SEM) coupled with an energy dispersive spectrometry (EDS) analysis indicated that the Fe3O4 and MnZnFe2O4 nanoparticles were uniformly coated on the surface of Fe powders. The co-existence of Fe3O4 and MnZnFe2O4 contributes to the preferable distribution of nano-sized insulation powders and excellent soft magnetic properties of soft magnetic composite (SMC) with high saturation magnetization Ms (215 A·m2/kg), low core loss (178.7 W/kg measured at 100 kHz, 50 mT), and high effective amplitude permeability of 114 (measured at 100 kHz). Overall, this work has great potential for realizing low core loss and outstanding soft magnetic properties of Fe-based powder cores.

MgO insulation coating with thickness of ca. 50nm was evaporated on the surface of iron powder and fabricated soft magnetic composite(SMC) with low iron loss. The MgO insulation coating had greater heat resistance than conventional phosphate insulation coating, which enabled stress relieving annealing at higher temperature (600C). Electrical and magnetic properties of SMC was examined. The electrical resistivity of the SMC annealed at 700C was 21μΩm. The iron loss at 50Hz for Bm = 1.5T was 5.34W, which was 40% of conventional SMC and was at the same level with laminated steel plate (t0.35). These results show that MgO insulation coating has enough heat resistance and adhesiveness to powder surface to obtain SMC with low iron loss.
