Grain boundary diffusion technology is to use surface coating, magnetron sputtering, vacuum evaporation, electrophoretic deposition, etc., to form the thin layer of Dy or Tb on the surface of thin sintered NdFeB magnets with a thickness of less than 9mm, and then pass through proper heat treatment and tempering treatment . The intrinsic coercivity of the neodymium magnets is greatly improved after that. The method helps to reduce the use of heavy rare earths, thus reduce the manufacturing cost, and can also produce high-performance magnet that cannot be achieved by normal processes.
Laminated magnet assembly is featured of small vortex , while remaining the same or even higher performance as normal magnet assembly. The laminated neodymium magnets could be used as rotor magnet of motor, especially in electric car. Thus it is more and more applied in insulated stitching magnet components .
