现役飞机的铝合金结构腐蚀问题很普遍，尤其是在海洋服役环境下。采用当量加速腐蚀试验的方法模拟飞机服役环境对2B06和7B04两种新型铝合金材料进行加速腐蚀试验，检测这两种型号铝合金材料不同腐蚀年限的腐蚀损伤数据，并分别对这些腐蚀数据进行统计分析，得到2B06和7B04两种新型材料的腐蚀损伤规律，为飞机结构的腐蚀损伤修理及现役飞机的剩余寿命评定提供数据及理论基础。

It’s very widespread that the aluminum alloy aircraft structure suffers the corrosion damage under the marine environment particularly. The equivalent accelerated corrosion test of the new aluminum alloy 2B06 and 7B04 was carried out. Corrosion damage was inspected and measured through microscope. The rule of the corrosion damage can be obtained by statistical analysis, and it can provide data and theoretical basis for the corrosion damage repair and the calendar life evaluation.
