| 目的 研究海洋环境对典型接地柱防腐蚀安装设计的影响。方法 以×型飞机某半封闭关键部位安装的接地柱为研究对象，设计三种防腐蚀安装方法，并在实验室环境谱下开展加速腐蚀试验，借助宏观、微观检测及接触电阻测试，对不同类型的试验件开展检测与测试。结果 两周期实验室加速试验结束后，采用直接安装模式的接地柱因底座腐蚀而无法检测接触电阻；采用填角安装模式的接地柱外观腐蚀严重，但其内部仍为电接触；采用封包安装模式的接地柱其内部被密封剂保护完好。结论 三种接地柱防腐蚀安装设计方法各有利弊，可根据结构的局部环境特点视情选择。 |
| 英文摘要: |
| The work aims to study the influence of marine environment on the anti-corrosion installation design of typical ground column. Three kinds of anti-corrosion installation methods were designed by taking the ground column installed in a semi-closed key part of type x aircraft as the research object, and accelerated corrosion tests were carried out under the laboratory environment spectrum. Different types of test pieces were detected and tested by means of macroscopic and microscopic tests and contact resistance tests. At the end of the 2 cycles of accelerated test in the laboratory, the contact resistance of the ground column with the direct installation mode could not be detected due to the corrosion of the ground column base. The ground column with the filling installation mode had a serious corrosion appearance, but its internal electrical contact was still kept. The ground column with the package-mounted mode was well protected internally by sealant. There are advantages and disadvantages of the three methods of ground column installation design, which can be selected according to the local environmental characteristics of the structure. |
