Method for manufacturing rare earth permanent magnet and rare earth permanent magnet |
| abstract |
The present invention provides a rare earth which can improve the coercive force obtained by Cu and can suppress the decomposition of the main phase or the precipitation of αFe without deteriorating the magnetic properties even when calcined in a hydrogen atmosphere. Permanent magnet and rare earth permanent magnet manufacturing method. The formed body obtained by pulverizing and molding the magnet raw material containing no Cu is held in a hydrogen atmosphere at 200 ° C to 900 ° C for several hours to several tens of hours to carry out calcination treatment. Thereafter, the formed body is sintered by vacuum sintering or pressure sintering, and Cu is sputtered on the surface of the sintered body to produce a permanent magnet. |
