【摘要】 NdFeB磁体以其优良的磁性能获得了广泛应用,然而其耐腐蚀性差、易氧化等缺点在一定程度上限制了NdFeB磁体的应用。本文提出一种新型柔性磁体,即压延成型时在柔性NdFeB磁体表面压合铁氧体制备铁氧体/NdFeB压合型复合柔性磁体来改善NdFeB磁体的耐腐蚀性。在80℃×1h腐蚀试验后,柔性NdFeB磁体增重率达0.11%,最大表面磁场损失率为5.88%;而压合柔性磁体的这两项指标分别为0和3.05%。另外,压合柔性磁体的耐水锈性良好。更多还原

【Abstract】 The flexible NdFeB magnet has found wide applications for its excellent magnetic properties, but the bad oxidation and corrosion resistance limits its usage to some extent. This paper proposed a new kind of flexible magnet which is called ferrite/NdFeB rolled flexible magnet with improved environmental performance. The weight gain rate of the flexible NdFeB magnet is 0.11%, and the decrease of the maximal superficial magnetic field is 5.88% after 80℃×1h corrosion test; however the two data of the ferrite-NdFeB rolled flexible magnet are 0 and 3.05%, respectively. Furthermore, the ferrite/NdFeB rolled flexible magnet exbits better water resistance than the pure flexible NdFeB magnet.更多还原
