摘　　要：磁粉芯又称软磁复合材料(SMC),因其具有高饱和磁感应强度、低矫顽力和磁芯损耗等优异的软磁性能而被广泛应用于电感元件和变压器。国内磁粉芯行业起步较晚,经过多年发展仍与国际先进水平有较大差距,特别是高端钼坡莫合金(MPP)磁粉芯市场被国外企业垄断。因此我国亟需在制备工艺上实现突破,以打破外国垄断,这也需要科研工作人员深入研究,突破理论和技术上的瓶颈。简述了磁粉芯的起源、发展,以及磁粉芯的种类,并对磁粉芯的制备工艺和参数对其性能的影响进行了重点阐述和分析,最后对磁粉芯的应用进行了论述,分析了我国MPP磁粉芯的发展前景,为磁粉芯的研制提供参考。Magnetic powder core is also known as soft magnetic composite material(SMC).It is widely used in inductors and transformers because of its excellent soft magnetic properties such as high saturation flux density,low coercivity and core loss.Domestic magnetic powder core industry started late,after years of development is still a big gap with the international advanced level,especially high-grade Molybdenum Pomoalloy(MPP)magnetic powder core market is monopolized by foreign enterprises.Therefore,China urgently needs to achieve breakthroughs in the preparation process to break the foreign monopoly.This also requires in-depth research by researchers to break through theoretical and technical bottlenecks.The origin and development of magnetic powder core and the types of magnetic powder core are briefly described.The influence of the preparation process and parameters of magnetic powder core on its performance is emphatically expounded and analyzed.Finally,the application of magnetic powder core is discussed.The development prospect of MPP magnetic powder core in China is analyzed,which provides reference for the development of magnetic powder core.
