摘要
大型天线广泛地应用在航空航天、深空探测、广播通信等领域,成为信息传递必不可少的设备。其多采用金属材料制造,因此在长期的室外工作环境下,极易发生腐蚀。金属材料的腐蚀将严重影响天线的性能和外观,甚至会产生人员与设备的安全问题。本文结合实际情况通过分析天线腐蚀的必要性、腐蚀机理和影响因素,结合实际情况为天线的防腐提供了优化材料、结构、加工工艺设计、喷镀金属涂层防护、涂料涂装防护、运输安装过程的防护、已损坏防护层的修复等方法,实现天线的长效防腐。
Large Antennas have been widely used in the aerospace, deep-space exploration and broadcast, which are essential in the communication. They are fabricated by metal, which can be easily corroded. Corrosion will deteriorate the appearance and performance, even cause the security problem. By analyzing the necessary, theory and influence factors of antenna corro- sion, many methods are proposed, which contains optimizing materials, structures, designs, coatings, and transportation.
