摘要： The present invention provides a rare-earth magnet capable of enhancing a corrosion resistance. A protective film is a three-layer film including a first protective layer with a crystalline structure α (for example, a polycrystalline structure), a second protective layer with a crystalline structure β (for example, a columnar-crystalline structure), and a third protective layer with the crystalline structure α from the side near a magnet body. Since the adjoining first and second protective layers have different crystalline structures from each other, and the adjoining second and third protective layers have also different crystalline structures from each other, compactness among the three layers in the protective film may be improved. Therefore, development of a pinhole is restrained, and corrosion of the protective film can be restrained.
摘要翻译：本发明提供一种能够提高耐腐蚀性的稀土类磁体。保护膜是包括具有结晶结构α（例如，多晶结构）的第一保护层，具有结晶结构β的第二保护层（例如柱状结晶））的三层膜，以及具有从靠近磁体的一侧的结晶结构α的第三保护层。由于相邻的第一和第二保护层具有彼此不同的晶体结构，并且相邻的第二和第三保护层也具有彼此不同的晶体结构，所以可以提高保护膜中的三层之间的紧密度。因此，能够抑制针孔的发展，能够抑制保护膜的腐蚀。

摘要： A rare earth magnet having excellent corrosion resistance is provided. It has a magnet body (10) containing a rare earth element, and a protective film (20) formed on the magnet body (10). In the protective film (20), a first protective film (21), a second protective film (22) and a third protective film (23) are laminated in this order from the side of the magnet body (10). These are in a polycrystalline state and composed of a metal plated film, for example. The first protective film (21) and the third protective film (23) have a smaller mean crystal grain size than that of the second protective film (22). Microcrystallization of the first protective film (21) can improve the density of the interface between the protective film (20) and the magnet body (10), and decrease the number of pinholes.
