| 摘 要： | 为解决Fe-Cr纤维提取过程中容易造成空气污染的问题,使得到的纤维具有较高的磁学性能,采用化学萃取法腐蚀掉Cu-13Fe-2Cr原位复合材料中的铜基体,制备了Fe-Cr金属纤维;通过调整硝酸与双氧水比例抑制NO2的产生;通过改变清洗方式使纤维具有较高的磁性。用SEM进行了形貌观察和成分能谱分析,用振动样品磁强计VSM作出了纤维的磁滞回线。结果表明,NO2被成功抑制,纤维的比饱和磁化强度保持在150 A.m2.kg-1左右。

| Abstract: | In order to gain higher magnetic performance and solve air pollution problems in extraction process of Fe-Cr fibers,cupreous body of Cu-13Fe-2Cr in situ composite materials were corrupted by using chemical extraction.NO2 generation was inhibited via proportion adjustment of HNO3 and H2O2.Higher magnetic performance was acquired by changing washing modes.Morphology was observed and component was analysed with scanning electron microscope,while hysteresis loops mapping were made by VSM.Finally,NO2 was inhibit... |
