摘要

随着通讯技术和武器装备的不断更新换代，吸波材料扮演的角色越来越重要，近些年对吸波材料的研究迎来迅速发展。羰基铁具有高饱和磁化强度和低生产成本等特点，因此被广泛用于制备吸波材料，但由于羰基铁吸收剂的表面活性较高，在海洋环境或高温环境下容易发生腐蚀或高温氧化，严重影响其吸波性能，随着装备对吸波材料的要求不断提高，羰基铁吸收剂的耐腐蚀、耐氧化改性技术逐渐成为研究热点。重点介绍了羰基铁吸收剂表面改性技术的研究进展，研究表明表面包覆改性可以提高羰基铁吸收剂的耐腐蚀、抗氧化性能，部分改性方法还可以改善材料的吸波性能。在兼顾耐高温氧化和耐腐蚀性能的基础上，发展厚度薄、吸收频段宽的吸波材料是未来发展的主要方向。

Abstract

With the continuous upgrading of communication technology and weapon equipment，the role of absorbing materials has become increasingly important，and the research on absorbing materials has rapidly developed in recent years.Carbonyl iron is widely used in the preparation of absorbing materials，owing to its high saturation magnetization and low production cost.However，due to the high surface activity of carbonyl iron absorbents，they are prone to corrosion or high-temperature oxidation in marine or high-temperature environments，which seriously affects their absorption performance.As the requirements for absorbing materials of equipment continue to increase，the corrosion and oxidation resistant modification technologies of carbonyl iron absorbers have gradually become a research hotspot.Herein，this article focused on the research progress of surface modification technology of carbonyl iron absorbers.Research showed that the surface modification of coatings could improve the corrosion resistance and oxidation resistance of carbonyl iron absorbers，and some modification methods could also improve the microwave absorption performance of materials.Besides，on the basis of balancing high temperature oxidation resistance and corrosion resistance，the development of absorbing materials with thin thickness and wide frequency band would be the main direction of future development.

Key words： absorbing material; carbonyl iron; surface modification; corrosion resistance; oxidation resistance
