摘要
In this paper, the Fe-9Si-6Al soft magnetic composite has been prepared via powder particles coated with aluminum oxide and silicone. The magnetic properties and microstructure of Fe-Si-Al SMC has been investigated. Results showed that the powder particles surface contained a thin insulating layer made of aluminum oxide and silicone. After annealed at 800 degrees C for 60min, the particles of component are all by themselves and the insulating layer is not destroyed. The Fe-Si-Al SMC has excellent magnetic properties. The magnetic permeability is steady with the frequency changing at 5kHz-100kHz range.
