Abstract

The influence of nitriding on the static magnetic properties, electromagnetic parameters and microwave absorption properties of Y₂Fe₁₂Co₄Si alloy were investigated. The results demonstrated that nitriding improved the electromagnetic parameters and microwave absorption properties of the Y₂Fe₁₂Co₄Si alloy. The improvement of electromagnetic parameters is due to an increase in the Snoek limit and the polarization of the Y₂Fe₁₂Co₄Si alloy due to nitriding. The nitrided sample exhibits better impedance matching performance and electromagnetic loss capability due to its higher electromagnetic parameters. With a thickness of 1.23 mm, the maximum effective absorption bandwidth achieves 6.91 GHz (11.00–17.91 GHz), and the minimum reflection loss reaches –55.9 dB.

氮化Y2Fe12Co4Si合金优异的微波吸收性能

研究了氮化对Y2Fe12Co4Si合金静态磁性能、电磁参数和微波吸收性能的影响。结果表明，氮化处理改善了Y2Fe12Co4Si合金的电磁参数和微波吸收性能。电磁参数的改善主要是由于氮化提高了Snoek极限和Y2Fe12Co4Si合金的极化。氮化样品具有较高的电磁参数，具有较好的阻抗匹配性能和电磁损耗能力。厚度为1.23 mm时，最大有效吸收带宽达到6.91 GHz (11.00-17.91 GHz)，最小反射损耗达到-55.9 dB。
