More information: Seol-mi Lee et al, A novel two-step grain boundary diffusion process using TaF5 and Pr70Cu15Al10Ga5 for realizing high-coercivity in Nd-Fe-B-sintered magnets without use of heavy ...

Nd-Fe-B magnets used in EVs operate at high temperatures of 150 – 200oC and need to exhibit high resistance to demagnetization, a capability that pure Nd-Fe-B magnets do not have.

The grain boundary diffusion process is a key technology designed to enhance the performance of permanent magnets. In this process, the heavy rare-earth materials is coated to the surface of the ...
