摘要(Abstract)：

采用有机硅树脂作为粘结剂制备了纯Fe软磁复合材料，研究了粘结剂含量、压制压力对纯Fe软磁复合材料微观结构和软磁性能的影响。结果表明，有机硅树脂作为绝缘粘结剂能有效包覆在粉末表面，经过500℃热处理后仍能稳定存在，制备得到的纯Fe软磁复合材料具有良好的软磁性能。当有机硅树脂添加量为1%，μ_(max)为222；当有机硅树脂添加量在2%时损耗最低，P_(cm)(1 T,1 kHz)=128.8 W/kg。当成型压力为1100 MPa时，μ_(max)为222。当压力为1.3 GPa时损耗最小：P_(cm)(1 T,1 kHz)=209.2 W/kg。

关键词(KeyWords)： 纯Fe软磁复合材料;粘结剂含量;成型压力;磁导率;涡流损耗
