- Abstract
In this paper, a novel soft magnetic powder core (SMPC) was successfully prepared by severally coating four kinds of organic binders on the surface of FeSiCrC micrometer powder. The effects of different organic binders with the same content on the micromorphology and soft magnetic properties of SMPC were studied in this experiment. The results show that the adhesive adhesion on the surface of FeSiCrC powder can effectively fill the air gap between FeSiCrC powder, which is conducive to the forming and compaction of magnetic powder core during the pressing process. The addition of organic binder can greatly improve the comprehensive soft magnetic properties of magnetic powder core. When 2-wt% silicone resin is added, its magnetic powder core has excellent magnetic properties, such as its low core loss (Pcv: 10 mT, 1000 kHz, 103.8 mW/cm3), high quality factor (Q: 625 at the peak), and high saturation magnetization. The different binders FeSiCrC magnetic powder cores prepared in this work are expected to be widely used in power applications and electronic products. It provides a new idea for the coating of magnetic powder core with organic binders.
