综合作者多年的飞机结构修理工作，分析、归纳了沿 海机场飞机典型腐蚀损伤，得出飞机结构腐蚀主要是环形间隙中未加保护的铝合金表面和间隙中的积水而形成的电化学腐蚀.提出缝隙密封等减少结构腐蚀的制造和使用维护过程中的防腐工艺措施.
The article summarizes the corrosion phenomena of aluminum alloys used for aircraft structural components,and points out that the occurrence of corrosion is mainly due to the effect of the unprotected surface of clearances around rivets or screws and the water in it.A physical model of corrosion is postulated.Furthermere,some protective measures are proposed for controlling the corrosion,which may be taken during design and manufacture of the components,as well as during service.
