Publication number: 20140113140Abstract: Provided are a coated cobalt powder and a preparation method thereof, the coated cobalt powder consisting of cobalt powder, and paraffin wax, polyethylene glycol or polyethylene coated on the outer surface of the cobalt powder. Using the coated cobalt powder to replace traditional cobalt powder as the raw material for preparing hard alloys, the dusts generated during production can be reduced, and the environment in a production shop can be improved; simultaneously, the paraffin wax, the polyethylene glycol or the polyethylene coated on the surface of the cobalt powder can effectively prevent the cobalt powder from being oxidized by the oxygen or water vapor in the air, thus improving the quality of the cobalt powder. The preparation process of the coated cobalt powder is free from contamination and the coated cobalt powder is suitable for industrialized production.Type: ApplicationFiled: July 28, 2011Publication date: April 24, 2014Inventors: Miaomiao Guo, Zhebo Ma, Xianda He, Jifeng Zhou, Yue Fu, Cong Liu

COMPOSITE SOFT MAGNETIC POWDER, COMPOSITE SOFT MAGNETIC POWDER CORE, AND PREPARATION METHOD THEREFOR
Publication number: 20140104023Abstract: The present invention discloses a composite soft magnetic powder core and a preparation method therefor, which belong to the technical fields of soft magnetic materials and preparation thereof. An Fe/Fe3O4 shell layer is generated in situ on surfaces of iron powder particles through a controlled oxidation process, to prepare Fe/Fe3O4 composite soft magnetic powder having a uniform structure. The Fe/Fe3O4 composite soft magnetic powder is mixed with suitable amount of silicone resin, and prepared into a high-performance Fe/Fe3O4 composite soft magnetic powder core by using a powder metallurgy compaction process. Such magnetic powder core has a high density, a high magnetic conductivity, a high magnetic flux density, a low loss, and a high breaking strength, and is useful in a large-power and low-loss application scenario. The present invention has the advantages of being rich in raw material resources, simple in process and environmentally friendly, and being suitable for industrial production.Type: ApplicationFiled: September 23, 2011Publication date: April 17, 2014Inventors: Bai Yang, Ronghai Yu, Satoshi Okochi, Daisuke Okamoto
