ANTICORROSION MEASURES FOR COMBINATIONAL TYPE OF GALVANIC CORROSION WITH CREVICE CORROSION
缝隙腐蚀与电偶腐蚀的混合型腐蚀形态与防腐措施

According to statistic analysis of corrosion damage of the civil aircraft in china,it is found that the corrosion damage in varying degrees occurred in the structural components using plate nuts.In this paper,the reason and the mechanism for this corrosion damage are studied,and preventive measures for this corrosion are suggested.These anticorrosion measures provide valuable reference for the anticorrosion design and repair of the aircraft structure.The practice proved that these anticorrosion measures have good effectiveness.
