摘要: 从软磁复合材料的磁性基体设计、绝缘包覆处理和新型制备技术3个方面对软磁复合材料的研究现状进行综述,得出:磁性基体设计时通过对不同特性的磁粉进行性能互补或对基体形态进行控制都可以有效地提高软磁复合材料的密度和磁导率;经绝缘包覆处理可以提高软磁复合材料的电阻率,从而降低其涡流损耗,但是非磁性相绝缘材料的加入会导致复合材料磁导率和饱和磁化强度降低;采用等离子烧结、微波烧结、激光烧结等新型制备技术可以有效改善软磁复合材料的性能.目前软磁复合材料的综合性能已无法满足电子元器件高频化、微型化的发展需求,未来应将研究重点放在优化基体成分设计与粒度配合、开发新的绝缘包覆材料、创新制备工艺、优化制备工艺参数、完善现有理论模型等方面.Abstract: The research status from magnetic substrate design, insulation coating treatment and new preparation technology were reviewed.It pointed out that the density and resistivity of soft magnetic composites could be effectively improved by using magnetic powders with different characteristics to complement the performance or controlling the morphology of the substrate during the design of the magnetic substrate. The insulation coating treatment could be used to increase the resistivity of the soft magnetic composite to reduce eddy current loss, but the addition of non-magnetic phase insulation materials would lead to a decrease in the magnetic permeability and saturation magnetization of the material. The optimized new preparation technology could effectively improve the performance of soft magnetic composite materials, such as plasma sintering, microwave sintering and laser sintering. The current comprehensive performance of soft magnetic composite materials could not meet the development needs of high frequency and miniaturization of electronic components.The future research directions would be further optimization of substrate component design and particle size coordination, development of new coating materials, innovative preparation processes, optimization of process parameters, and perfection of theoretical models.
