| titleOfInvention | R-T series permanent magnet |
| abstract | Main phase consisting of R 2 T 14 B crystal grains, wherein R is one or two or more of the rare earth elements, and T is one or two or more transition metal elements in which Fe or Fe and Co are essential And a sintered body including at least a grain boundary phase containing more R than the main phase, and having a hydrogen concentration of 300 ppm or more at the surface layer portion thereof and having a thickness of 300 μm or less (not including 0). The magnetic body 2 having the rich layer 21 formed thereon and the RTB permanent magnet 1 having the protective film 3 coated on the surface of the magnet body 2 do not deteriorate the magnetic properties. The corrosion resistance of the RTB permanent magnet 1 in which the protective film 3 was formed can be improved. It is also applicable to the formation of the protective film 3 by electroplating, and it is possible to sufficiently secure the corrosion resistance, which is the original purpose of the formation of the protective film 3, with almost no deterioration in production efficiency. The partial collapse (separation) can be suppressed to provide the RTB permanent magnet 1 with high dimensional accuracy.n n n n Corrosion Resistance, Barrel Treatment |
