MAGNETICALLY ACTIVE COATINGS FOR ELECTRICAL MATERIALS

DOI: 10.17804/2410-9908.2022.5.006-014

The prospects of using nitride-oxide and magnesium phosphate electrical insulating coatings on thin strips of magnetically soft alloys based on silicon iron are considered. X-ray diffraction topography, powder figures, and magnetic measurements have shown that coatings create uniformly distributed tensile stresses in materials, increase uniaxial magnetic anisotropy, and reduce the volume of transversely magnetized domains and the width of longitudinally magnetized ones. This increases magnetic permeability and significantly decreases the coercive force, as well as eddy-current and total (by 20–25 %) magnetic losses. Tensile (magnetically active) coatings enhance the effect of subsequent thermomagnetic treatment of alloys.

Acknowledgments: The work was performed under a state assignment from the Russian Ministry of Education and Science, themes Magnet, No. 122021000034-9, and Diagnostics, No. 122021000030-1.
