飞机在地面停放时主要受到腐蚀损伤,在空中工作时主要受到疲劳损伤,飞机重复经历停放和起飞的过程更接近地面腐蚀和空气疲劳的交替状态.因此,对近年来航空铝合金的腐蚀与疲劳交替研究现状进行综述和总结.首先介绍了腐蚀与疲劳交替裂纹萌生机理,然后根据铝合金腐蚀与疲劳交替研究进展,介绍了腐蚀与疲劳交替实验的分类和加速方法,同时总结了腐蚀与疲劳交替对寿命的影响及其寿命预测模型,并对未来发展趋势进行展望.
Research Status of Alternating Corrosion and Fatigue of Aviation Aluminum Alloys
The aircraft is mainly subject to corrosion damage when it is parked on the ground and fatigue damage when it is working in the air.The repeated parking and takeoff process of the aircraft is closer to the alternating state of ground corrosion and air fatigue.Therefore,the research status of corrosion and fatigue alternation of aviation aluminum alloys in recent years was reviewed and summarized.First,the initiation mechanism of alternating corrosion and fatigue cracks was introduced.Then,according to the research progress of alternating corrosion and fatigue of aluminum alloys,the classification and acceleration methods of alternating corrosion and fatigue experiments were introduced.At the same time,the impact of alternating corrosion and fatigue on life and the life prediction model were summarized,and the future development trend was prospected.
