Abstract

Based on the effect of air humidity and temperature, salt fog, solar radiation, acidic atmosphere, sand and dust and mechanical environment (tensile and bending fatigue, vibratory fatigue and frictional wear) on the corrosion resistance of aircraft, the work aims to analyze the damage mechanism of the coupling of corrosion and electrical stress, corrosion and frictional wear, corrosion and mechanical stress. The difficulties and countermeasures of aircraft anti-corrosion design in a multi-factor coupling environment were proposed. It was pointed out that the coupling effect of corrosion and electrical stress, frictional wear, and mechanical stress was the difficulty in the design of corrosion and should be given special attention.

Key words
