The combination of Co and (TbAl) diffusion increases coercivity and remanence in Nd-Fe-B magnets, leading to better overall magnet performance.
Results show a significant enhancement, with coercivity values exceeding 10 kOe and temperature coefficients of remanence improving substantially.
Assessment using grain boundary diffusion methods demonstrates potential to optimize magnetic properties effectively and efficiently in sintered magnets.
Highlights the promise of this diffusion approach for future applications in high-performance magnet technologies.
