| 摘要: |
| 海洋盐雾大气环境下,结构直接暴露在大气环境中，可能会遭遇高温、高湿及雨淋等环境条件。通过真实环境浸泡试验和暴露试验，验证在不同防水措施下的不同材料/表面处理的紧固件耐腐蚀性能，并对试验中钛合金螺栓承载力偏低现象进行了分析。 |

| Abstract: |
| In ocean salt fog atmosphere environment, the whole structure is exposed directly to open atmosphere, and may suffer environment conditions such as heat, humidity and rain etc. In this work,soaking and exposing experiments is carried out in a true environment at launch site, verifying the bearing corrosion function of fasteners to waterproof measure under different material and surface handles. And analysis on low loading phenomenon of titanium alloy bolts in the experiment is conducted. |
