Abstract

Abstract: A new method of depositing an insulating multifunctional oxide coating on metal particles was developed. Such coatings increase corrosion resistance and insulate metal particles from each other. On base of capsulated by oxide coating water-atomized iron powder ASC100.29, new composite soft magnetic materials were synthesized, which are able of replacing electrical steel in devices. Structural, electromagnetic properties and corrosion characte-ristics of the obtained composites were studied. It was found that the synthesized composite materials have low electromagnetic losses, high values of magnetic induction(up to 2.1 T) and good corrosion resistance. The results demonstrate that the use of such materials in power supplies, chokes, transformers, stators and rotors of electric machines and other products ensures their stable operation under various conditions.

Key words: Soft magnetic composite material, Iron powder, Insulating cover, High-frequency transformer, Stators and rotors of electro machine
