研究了铁粉纯度和粒径对磷化铁粉软磁复合材料磁性能的影响。结果表明,铁粉经磷化后,表面成功包覆了完整均匀的磷酸盐绝缘层。铁粉纯度提高,软磁复合材料磁芯的密度和磁导率增大,同时磁滞损耗降低。铁粉粒度增大,磁芯密度和磁导率增加,中高频率下磁损耗明显增加,且频率越高越明显。
This paper investigates the effect of iron powder purity and particle size on the magnetic properties of phosphated iron soft magnetic composites（SMC）.The results showed that the phosphating process give rise to a large coverage of the iron powders surface by the iron phosphate coating.The density and permeability of phosphated iron samples shows an increase with increased the iron powder purity or particle size.The sample with higher iron powder purity exhibits lower hysteresis loss.With increase in the particle size,magnetic loss increases significantly at medium and high frequencies,and the higher the frequency the more obvious.
