微动是指两个看起来静止的接触表面发生极小振幅的相对运动,在腐蚀环境下的微动称为微动腐蚀,微动腐蚀在微动和腐蚀的协同作用下极大地增加了接触构件间的机械和化学损伤.由于海军飞机服役环境的复杂性,飞机机身铆接和销钉连接的构 Fretting refers to the relative motion of two seemingly static contact surfaces with very small amplitudes. Fretting in corrosive environments is known as fretting corrosion, and fretting corrosion greatly increases contact under the synergistic action of fretting and corrosion Mechanical and chemical damage between components Due to the complexity of the service environment of the Navy’s aircraft, the structure of aircraft fuselage riveting and pinning
