摘要:
金属软磁复合材料(SMCs)是电力电子元器件的关键基础材料,在能源、信息、交通、国防等重要领域应用广泛。本文围绕软磁复合材料合金磁粉和绝缘包覆层两个主要方面展开综述。在合金磁粉的成分设计方面,分别从晶态、非晶和纳米晶软磁合金体系出发,对比了合金元素对磁粉微结构,以及饱和磁化强度、矫顽力、磁晶各向异性、磁致伸缩系数和电阻率等性能的影响,提出了不同体系合金磁粉的设计原则。在绝缘包覆方面,分别阐述了有机、无机和有机无机复合包覆的最新研究进展,分析了不同绝缘包覆方法的机理和关键制备参数对于绝缘层组分、结构及复合材料综合性能的作用规律,展望了绝缘包覆工艺的发展趋势。在此基础上,本文提出了软磁复合材料的发展方向。
Abstract:
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.
