| titleOfInvention | Fe-Ｂ-R permanent magnets having a corrosion resistant coating and a method of manufacturing the same |
| abstract | The Fe-B-R permanent magnet has a metal oxide film having a thickness of 0.01 μm to 1 μm on its surface with a metal film interposed therebetween. Thus, the film is excellent in adhesion to the surface of the magnet. Even if the permanent magnet is left to withstand high temperature and high humidity at a temperature of 80 ° C. and a relative humidity of 90% for a long time, the magnetic properties of the magnet cannot be deteriorated. The magnet has sufficient thermal shock resistance to withstand long term heat cycles in the temperature range of -40 ° C to 85 ° C and exhibits stable high magnetic properties. Therefore, the Fe-B-R permanent magnet having a corrosion resistant film free of hexavalent chromium can be produced. |
