Latest Patents
One of Zhi'an Chen's latest patents is titled "Rare earth permanent magnet and method for preparing same." This invention discloses a rare earth permanent magnet that exhibits a heavy rare earth element volume diffusion phenomenon. This phenomenon occurs at a depth of 5 μm to 100 μm from the surface of the magnet, creating a volume diffusion layer region. The region is divided into magnet units with a volume of 10*100*5 μm, where the concentration difference of heavy rare earth elements is maintained below 0.5 at %. The invention provides a sintered NdFeB magnet with high intrinsic coercive force (Hcj) without affecting the remanence (Br) and the maximum magnetic energy product (BH)max. The method for preparing this magnet involves microwave heat treatment on a blank magnet coated with heavy rare earth source slurry in a vacuum condition. This innovative method enhances heating efficiency, reduces heat treatment time, lowers energy consumption, and decreases production costs.
