摘　　要：微动广泛存在于航空航天等各种机械构件中,加速构件接触表面及表层裂纹的萌生与扩展。由于海军飞机服役环境的复杂性,铝合金构件腐蚀相当严重,因此了解铝合金微动腐蚀规律具有极其重要的作用,有助于减少微动腐蚀,为老龄飞机的维护提供更多技术指导。本文结合微动损伤理论分析了铝合金在大气和盐水中的微动特性,总结了微动磨损过程主要的损伤机制。Fretting usually occurs in the structure of aeronautics and astronautics,and accelerates expansion of cracks about the surface of structures.Because of the complexity of the surrounding of aircrafts,the corrosion of aluminum alloy structures is great serious,so it is very important to understand the discipline of fretting corrosion about aluminum alloy,which may help to reduce fretting corrosion and offer more technology help of maintenance about older airplane.The paper analyses the property of fretting corrosion about aluminum alloy in air or in saline condition on the basis of fretting damage theory,and summarizes the main damage mechanisms of fretting wear.
