Abstract

In this study, we investigated how adding nanopowders to a micropowder affects the packing fraction and permeability. The micropowder used was a Fe-Ni crystalline alloy, which was sieved to less than 38 μm to minimize the effect of particle size distribution. The nanopowders, magnetic Ni and nonmagnetic Zn, were added to the Fe-Ni at weight ratios of 95:5, 90:10, 85:15, and 80:20. The results showed that the permeability of Fe-Ni was higher when sieved to 38 μm compared to the overall particle size. When the magnetic Ni nanopowder was added to the Fe-Ni powder sieved to 38 μm, both the packing fraction and permeability increased up to a ratio of 85:15 and then decreased. On the other hand, when the nonmagnetic Zn nanopowder was added, the packing fraction increased up to a ratio of 85:15 and then decreased, while the permeability continued to decrease.

铁-镍/纳米粒子（镍、锌）软磁复合材料的渗透性调制

在这项研究中，我们探讨了在微粉中添加纳米粉体如何影响填料分数和渗透性。使用的微粉是铁镍结晶合金，经过筛分后粒径小于 38 μm，以尽量减少粒径分布的影响。纳米粉末、磁性镍和非磁性锌分别以 95:5、90:10、85:15 和 80:20 的重量比添加到铁-镍中。结果表明，与整体粒径相比，当筛分至 38 μm 时，Fe-Ni 的渗透率更高。当将磁性纳米镍粉添加到过筛至 38 μm 的镍铁粉中时，堆积分数和渗透率都会增加，最高比例为 85:15，然后降低。另一方面，当加入非磁性纳米 Zn 粉末时，填料分数增加到 85:15 的比例，然后下降，而渗透率则继续下降。

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
