| 目的 研究某型飞机腐蚀关键结构防护涂层体系的腐蚀失效行为,评估涂层的防护性能,为整机日历寿命体系评定和飞机大修提供试验依据。 方法 在编制加速环境谱的基础上,对模拟件进行环境谱作用下的加速腐蚀试验。 结果 在经过修理前后两个阶段的加速腐蚀后,模拟件在铆钉连接区域表面涂层均出现不同程度的鼓包、开裂、剥落等老化现象。 结论 腐蚀关键结构表面防护涂层体系总体上能够满足首翻期和翻修间隔期内结构的表面防腐要求, 但在外场使用维护中应针对铆钉、螺钉连接件周围等腐蚀敏感部位加强防护,一旦出现涂层老化、破损等损伤需要及时进行局部修复。 在科学、合理的外场使用维护条件下,可以适当延长飞机的进厂大修时间。 |

| Objective To study the corrosion failure behavior and evaluate the protection property of the coating for the corrosion critical component on a certain type of aircraft, and to provide test proofs for determining the calendar life of airplane and formulating maintenance compendium. Methods On the basis of compiling accelerated corrosion environment spectrum, accelerated corrosion experiments in typical accelerated corrosion environment were carried out. Results After accelerated corrosion for the two stages before and after repairing, there were bumps, cracks and exfoliation on the coating surface. Corrosion damage crowded at the joint section with rivets mainly. Conclusion Overall, the protective coating system on the surface of corrosion critical structure could meet the surface anti-corrosion requirements of the structure during the first restoring and the restoring interval periods. However, it would be necessary to enhance the coating protection for the corrosion critical joint section with rivets when used in field. And if corrosion damage was found on the coating of these areas during service, local repair should be implemented promptly. Under the condition of scientific use and maintenance, it would be possible to prolong the top overhauls interval. |
