摘要： The present invention provides a method for preparing a rare earth permanent magnet material. The preparation method of the present invention comprises atomizing spray process and infiltrating process, wherein the atomizing-sprayed sintered rare earth magnet is placed in a closed container before infiltrating. Through the atomizing spray process a solution containing a heavy rare earth element is coated on the surface of a sintered R1-Fe(Co)-B-A-X-M rare earth magnet, and after baking, heat treatment is performed to infiltrate the sprayed heavy rare earth element to the grain boundary phase of the sintered rare earth magnet. The preparation method of the present invention saves the amount of a heavy rare earth element used in the conventional process, and the production cost. In addition, the preparation method of the present invention could, in the premise that the remanence decreases very little, significantly increase coercive force of the magnet, and apparently decrease the remanence temperature coefficient and coercive force temperature coefficient of the magnet, and apparently improve resistance of the magnet against demagnetization at a high temperature.
