摘要

According to the present invention, a method for preparing a sintered rare earth-based magnet according to the present invention comprises the steps of: heating an R-Fe-B based magnet powder to a predefined temperature to produce a sintered magnet, wherein R is a rare earth element or a combination of rare earth elements; coating the surface of the produced sintered magnet with a coating solution prepared by mixing a heavy rare earth powder and a melting point depression element powder in a solvent; and heat-treating the coated sintered magnet. A heavy rare earth element is efficiently diffused on the interface of the sintered magnet to improve the coercive force of the sintered magnet.;COPYRIGHT KIPO 2017
