Improvement of coercivity of sintered NdFeB permanent magnets by grain boundary diffusion process
碩士 === 國立中正大學 === 物理學系暨研究所 === 101 === In this study, grain-boundary-diffusion (GBD) process via the usage of DyF3 powder on the surface of magnets was applied to the sintered NdFeB magnets. The effects of surface morphology, oxygen concentration, thickness and diffusion conditions on coercivity (iH...
