摘要
研究了烧结钕铁硼永磁体经液氮冷处理后的磁性能变化规律。35SH、35H、N40、N35四个牌号的烧结钕铁硼永磁体经液氮冷处理后,磁性能有不同程度的提高。
The effects of liquid-nitrogen cryogenic treatment on the magnetic properties are studied. After cryogenic treatment of liquid-nitrogen, the magnetic properties of four brands of sintered NdFeB magnets , 35SH, 35H, N40 and N35 are improved to different degrees.
