What is grain boundary diffusion technique?
With the wide application of sintered NdFeB materials in modern industry and electronic technology, especially in the fields of new energy vehicles, industrial robots and mobile intelligence, it is required that NdFeB products be developed towards lightness, thinness, miniaturization and high energy. The requirements for energy product, coercive force and thermal stability of magnets are getting higher and higher. However, under the traditional preparation process, the high coercive force and high magnetic energy product of sintered NdFeB have always had a trade-off.
