BONDED RARE EARTH MAGNET |
摘要 |
A bonded rare earth magnet which exhibits excellent magnetic properties for a long time is provided by improving oxidation resistance at high temperatures. The magnet has a magnet body (10) comprising magnet powder (11) containing a rare earth element and a resin part (12) binding the magnet powder (11) and having a structure in which the magnet powder (11) is embedded in the resin part (12); and an amorphous carbon film (91) formed directly on a surface of the magnet body (10), the resin part (12) comprising a binder resin part (14) binding the magnet powder (11); and a resin layer (13) serving as a surface layer of the magnet body (10) and covering the magnet powder (11). The binder resin part and the resin layer are formed of the same resin material and are continuous and integral with each other.
