摘要
在钐钴永磁体的大批量生产过程中,磁体经常出现明显裂缝和细微裂纹,导致磁体机械性能差,严重影响其应用。本文分析了裂纹的种类及产生原因,从降低生产过程中产生的内应力着手,提出了防止产生裂纹的改进工艺,取得良好效果。
In the mass production of SmCo permanent magnets, cracks often appear, which will cause the deterioration of mechanical behaviors and affect the application of the magnets. The for- mation and the causes of cracks were analyzed in this paper. An improved progress to prevent the formation of the cracks was provided, based on the efforts to reduce the internal stress in the production process.
