Title:
永久磁石材料の処理方法
Document Type and Number:
Japanese Patent JP6960527
Kind Code:
B2
Abstract:
The present disclosure discloses a method for the magnetism stabilizing treatment of a permanent magnet material. The method can include following steps: providing a permanent magnet material having a positive temperature coefficient of coercivity; magnetizing the permanent magnet material at a temperature T3 with a range of -200 degree centigrades to 200 degree centigrades; and performing a magnetism stabilizing treatment towards the permanent magnet material with temperature decreased in a range of the temperature T3 to a temperature T4, or at the temperature T3.
