| 摘 要： | 为制备高性能的软磁铁硅铝磁粉芯,研究了降低铁硅铝磁粉芯损耗的方法.采用扫描电镜、金相显微镜、B-H分析仪检测样品的内部结构、形貌、磁性能.研究结果表明,压制后的退火处理是降低铁硅铝磁粉芯损耗的关键,增加热处理温度能够有效地降低磁粉芯的涡流损耗和磁滞损耗,过高的热处理温度会增大涡流损耗,最佳的热处理温度区间为660~720℃;添加绝缘剂能够有效地提高磁粉芯的电阻,降低其涡流损耗,对磁滞损耗的影响不大;增大成型压力可降低铁硅铝磁粉芯的损耗和矫顽力,最佳的成型压力为1 800 MPa.

| Abstract: | To prepare the high-performance Fe-Si-Al soft magnetic powder cores,how to reduce the loss of Fe-Si-Al magnetic powder cores was explored.SEM,metallographic microscope and B-H analyzer were used to characterize the interior structure,morphology and magnetic properties of samples.The results indicated that the annealing following compaction is crucial to reducing the loss of Fe-SiAl powder cores,and increasing annealing temperature can effectively reduce both hysteresis loss and eddy current loss,but over-an... |
