Title:
TREATMENT METHOD FOR SOFT MAGNETIC METALLIC MATERIALS
Document Type and Number:
WIPO Patent Application WO/2020/098667
Kind Code:
A1
Abstract:
A treatment method for soft magnetic metallic materials, relating to the field of metallic materials. The treatment method comprises: applying a surface treating agent to a soft magnetic metal material by means of a heat treatment process to enhance the magnetic induction intensity of the soft magnetic metal material, wherein the surface treating agent comprises carbon and/or nitrogen; the soft magnetic metal material is an amorphous material, nanocrystalline, silicon steel, or pure iron. By means of the treatment method, the magnetic induction intensity of soft magnetic metal materials can be effectively improved, so that the application of the soft magnetic metal materials in the field of electricity has a greater advantage.
