Fe-based amorphous powder cores with low core loss and high permeability fabricated using the core-shell structured magnetic flaky powders
Journal of Magnetism and Magnetic Materials(2020)
摘要
•High-quality inorganic insulating layer was performed for industrial Fe-based amorphous flaky powders.•FeSiBCCr MFPCs show better magnetic properties and lower raw material cost than the Finemet MFPCs.•The FeSiBCCr MFPCs exhibit higher permeability and lower core loss than conventional FeSiB MFPCs.•The FeSiBCCr MFPCs annealed at 773 K for 0.5 h exhibit excellent comprehensive soft magnetic properties.
