摘要 针对吸波涂层氧化腐蚀现象,提出一种基于选择表面的周期结构涂层维修工艺。利用腐蚀法,在以羰基铁粉(CIPs)为吸收剂的吸波涂层表面制备CIPs及其氧化物涂层。用扫描电子显微镜(SEM)对腐蚀后颗粒的形貌进行了分析。测试了8~18GHz下混合颗粒的复介电常数和复磁导率,并用等效介质理论计算氧化涂层的参数。分析腐蚀和维修工艺对反射损耗(RL)的影响。结果表明:当CIPs涂层表面被氧化时,随着氧化涂层厚度的增加,涂层的吸波性能减弱,反射损耗增量值约为2dB。当涂层厚度为0.8mm时,维修效果不理想,若涂层厚度增加至1mm,且氧化涂层厚度为0.1mm时,维修效果较好,体现为10~18GHz频率范围内的吸波带宽增加,反射损耗相应减小约为2dB。

Abstract:The periodic structure coating maintenance process based on the selective surface was proposed. The coating of oxidized Fe and carbonyl iron particles (CIPs) was obtained by the corrosion method. The morphology of particles after corrosion was characterized by the scanning electron microscopy (SEM). The permittivity and permeability of the absorber adding the hybrid particles were tested in 8-18GHz, and the oxidized coating parameter could be calculated using the effective medium rule. Effects of the corrosion process and the maintenance process were analysed. The results show that as the CIPs oxidized in the coating surface, the coating's absorbing property was weakened as the oxidization thickness is increased, and the increment value of reflection loss (RL) is about 2dB. When the coating thickness is set as 0.8mm, the maintenance performance is unsuitable. However, if the coating thickness is increased to 1mm and the oxidization thickness is 0.1mm, the maintenance performance is improved, then the absorbing band can be widened in 10-18GHz and the RL decrement is about 2dB correspondingly.
