| 摘 要： | 采用高压水雾化工艺制备的Fe合金粉为原料，经高能球磨处理和后续真空退火处理制备薄片状外形和纳米晶微结构的Fe基合金吸收剂；选用改性聚氨酯为胶粘剂，以Fe基合金吸收剂为填料制备吸波涂层；并对Fe基合金吸收剂的微波电磁参量和吸波性能做了测量和分析评价。结果表明，基于铁基纳米晶薄片状吸收剂制备的吸波涂料在0．5～18GHz的微波宽频带具有良好的吸波性能（小于-10dB），可以应用于民用抗电磁辐射干扰和军事隐身技术领域。

| Abstract: | Nanocrystalline flakes of Fe-based alloy were synthesized by atomization process,high energy ball milling and sequent annealing.The microwave absorbing coating was made of the Fe-based alloy fillers and polyester. The microwave electromagnetic parameters and absorbing ability were measured. Results show that the coating made of the Fe-based alloy flakes presents favorable absorbing performance (lower than-10 dB) in the frequency range of 0.5～18 GHz. These materials can be applied in the field of anti-electromagnetic interfere and stealthy technology. |
