Korean researchers solve the thick-magnet coercivity problem with a sandwich-structured grain boundary diffusion process

Nd-Fe-B magnets have a scaling problem that limits high-power EV motor design: the grain boundary diffusion process that gives them high-temperature coercivity only works well near the surface. As magnets get thicker to handle higher torque and power, the core degrades while the exterior performs, meaning the interior of a Read more
