Influence of Pr-Al-Co alloy diffusion source on magnetic properties and microstructure of sintered Nd-Fe-B magnets processed by grain boundary diffusion
文献摘要：
In this study,the influence of the content of Al and Co in the diffusion source on the magnetic perfor-mance and microstructure of the diffused magnet was studied by grain boundary diffusion treatment with Pr70Al30-xCox(x=0 at％,10 at％,15 at％,20 at％,30 at％)alloys.When the Co content in the diffusion source increases from 0 at％to 10 at％,the coercivity enhancement in the Pr70Al20C010 diffused magnet is the highest,increased from 1.62 to 2.24 T,higher than 2.01 T of the Pr70Al30 diffused magnet.With further increase of Co content in the diffused source,the coercivity of the diffused magnet decreases gradually,the coercivity of Pr70Al15C015,Pr70Al20C010 and Pr70C030 diffused magnet is 2.15,1.99 and 1.81 T,respectively.Microstructural analysis shows that plenty of continuous grain boundary phases(CGBPs)can be formed in the Pr70Al20CO10 diffused magnet under the synergistic effect of Al and Co,which leads to the enhancement of magnetic isolation between more adjacent grains.However,the amount of CGBP in the diffused magnets gradually decreases with the further increase of Co content in the diffusion source.
