| 简介 |
The invention relates to a method for producing a rare earth magnet (2.1 to 2. n. 3.1 through 3. n) of a cuboidal semi-finished product (1), comprising two flat sides (a. 1. A.2) And four the flat sides (a. 1. A.2) Are provided on the edge side (a. 3), on the A.6 edge side, each starting from the two flat sides (a. 1. A.2), Which form magnetic poles and run orthogonally to the anisotropic magnetic orientation, is diffused at least substantially perpendicular to the flat sides in grain boundary-diffusion dysprosium or terbium into the semi-finished (1). The diffusion (D) is carried out in such a way that a concentration of the dysprosia or terbium starting from the two flat sides (a. 1, A.2) to a midpoint between the flat sides (a. 1. A.2) Of the semi-finished (1) in each case decreases. Then the semi-finished product (1) is divided into two parts (2, 3) in a cutting process. |
