羰基铁基复合材料的高效吸波-防腐双功能特性研究
Investigation on the dual functional properties of efficient microwave absorption and anti-corrosion of carbonyl iron-based composites
摘要
Abstract
As 5G and radar technologies evolve swiftly,the issue of electromagnetic contamination and the need for rapid,covert protection of specialized gear is increasingly critical.Materials that absorb ferromagnetic waves have become popular stealth materials due to their strong saturation magnetization and superior capacity to reduce electromagnetic waves.However,the practical use of ferromagnetic wave-absorbing materials has been significantly limited by corrosion issues in varied application settings.This document details the successful creation of a multistage carbonyl iron matrix composite,noted for its superior wave-absorbing and corrosion-resistant features,through a complex liquid-phase reaction.The material's minimal reflection loss reaches as much as-48.3 dB,while its effective absorption bandwidth extends to 7.0 GHz.Concurrently,there has been a notable enhancement in its ability to resist corrosion,evidenced by a substantial shift in the self-corrosion voltage Ecorr to-0.22 V and a reduction in the self-corrosion current density Icorr to 1.21×10-7 A/cm2,bolstering the prospects for developing innovative high-efficiency ferromagnetic wave-absorbing substances.Addressing issues related to electromagnetic pollution and the stealth of equipment holds immense importance.关键词
