  • Patent number: 10943731
    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.

  • Patent number: 10790076
    Abstract: A fixed beam 2 along which magnet-body holding sections 22 are consecutively provided is disposed so as to pass through a slurry 1. Sintered magnet bodies m placed in the magnet-body holding sections 22 by movable beams 3 are conveyed by repeating an operation in which the sintered magnet bodies m are moved to the following magnet-body holding sections 22. While being conveyed, the sintered magnet bodies m are passed through the slurry 1 to apply the slurry thereto, and are subsequently dried to remove a solvent in the slurry and affix a powder in the slurry thereto, and, as a result, the powder is continuously applied to the plurality of sintered magnet bodies.
