Title:
METHOD FOR PRODUCING RARE-EARTH MAGNETS, AND RARE-EARTH-COMPOUND APPLICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/175062
Kind Code:
A1
Abstract:
When sintered magnet bodies 1 are held in a jig 2 having a rotational axis in the vertical direction, immersed in a slurry 41 to apply the slurry thereto, rotated in conjunction with the jig to remove the surplus slurry on the surface of each of the sintered magnet bodies by centrifugal force, and subsequently dried to cause the surfaces of the sintered magnet bodies to be coated with a powder, the slurry is applied while the sintered magnet bodies are held such that no portion of any of the outer surfaces forming the contours of the sintered magnet bodies is orthogonal to the direction of the centrifugal force. As a result, the rare-earth-compound powder can be uniformly applied to the surfaces of the sintered magnet bodies.
