Microstructure and magnetic properties of Fe-Si-Al soft magnetic composite

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℃ 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.
