摘要： A resin bonded rare earth magnet, compression molded from rare earth-transition alloy powder and thermosetting resin, having a magnet 1 comprising a mixture of thermosetting resin and rare earth-transition alloy powder with a particle size of between 20 and 300 microns, a filling material 3 with particle size between 0.1 and 15 microns which is used to fill in the depressions 2 on the surface of said magnet 1 and is then fixed with said thermosetting resin, and a corrosion inhibiting coat 4 made from synthetic resin applied to the surface of said magnet 1 which has been rendered smooth by the application of said filling material into the depressions on its surface.
