金屬軟磁復(fù)合材料(SMCs)是電力電子元器件的關(guān)鍵基礎(chǔ)材料,在能源、信息、交通、國防等重要領(lǐng)域應(yīng)用廣泛。本文圍繞軟磁復(fù)合材料合金磁粉和絕緣包覆層兩個(gè)主要方面展開綜述。在合金磁粉的成分設(shè)計(jì)方面,分別從晶態(tài)、非晶和納米晶軟磁合金體系出發(fā),對(duì)比了合金元素對(duì)磁粉微結(jié)構(gòu),以及飽和磁化強(qiáng)度、矯頑力、磁晶各向異性、磁致伸縮系數(shù)和電阻率等性能的影響,提出了不同體系合金磁粉的設(shè)計(jì)原則。在絕緣包覆方面,分別闡述了有機(jī)、無機(jī)和有機(jī)無機(jī)復(fù)合包覆的最新研究進(jìn)展,分析了不同絕緣包覆方法的機(jī)理和關(guān)鍵制備參數(shù)對(duì)于絕緣層組分、結(jié)構(gòu)及復(fù)合材料綜合性能的作用規(guī)律,展望了絕緣包覆工藝的發(fā)展趨勢(shì)。在此基礎(chǔ)上,本文提出了軟磁復(fù)合材料的發(fā)展方向。

Soft magnetic composites are key materials for power and electronic devices with wide applications in energy, information, transportation and national defense. This work reviews the latest developments on the magnetic powders and insulation coatings as the two main components in the SMCs, based on which research directions of the SMCs have been pointed out. For the composition design of the magnetic powders, effects of different alloy elements on the microstructure and properties including saturation magnetization, coercivity, anisotropy, magnetostriction and electrical resistivity have been analyzed. Principles for the design of crystalline, amorphous and nanocrystalline magnetic alloy systems have been summarized. In terms of the insulation coatings, developments on organic, inorganic and hybrid coating methods have been reviewed. The research trend of the insulation has also been suggested based on revealing the insulating mechanism and the effects of key fabrication parameters on the component and structure of the coating as well as the performance of the SMCs.
