| 摘 要： | 采用聚乙烯醇做粘结剂,制备了Fe73.5Cu1Nb3Si13.5B9非晶磁粉芯。并用XRD、SEM等手段对其进行了表征。还对其磁性能进行了研究,结果表明:μ值随着粉体粒度的减小而减小,随着压力增大而增大;磁粉的粒径变小,粉芯的Bm值上升,Hc值增大;随着压力增大,粉芯的Bm值上升,Hc值则呈下降趋势。粉体粒度的变化对Q值影响不大。磁粉芯的中心频率为10MHz,其最大Q值为20。软磁粉芯在10MHz左右高频范围内,具有较好的应用价值。

| Abstract: | Fe73.5Cu1Nb3Si13.5B9 non-crystal magnetic powder cores were prepared with polyvinyl alcohol felt. The core was characterized by XRD and SEM. Its magnetic properties were measured, and obtained results show that (1) with the decrease of powder size, μ-value decreases, Bm and Hc increase; (2) with the increase of formed pressure, μ-value increases, Hc decreases; (3) the change of powder size is not influence on Q-value. |
