Important Form

Corrosion fatigue (CF) of aluminum alloy is an important form of aircraft structural damage. Considering the real service conditions, it is necessary to study the effects of the coating on the CF process. The CF lifetime tests were conducted in 3.5% NaCl solution. The coating could well protect specimens before it damaged and markedly improved the resistibility of CF. According to results of S-N fatigue curves, at σmax=250MPa, real-time detection of the CF process for LY12CZ aluminum alloy with and without coating was performed using digital acoustic emission (AE) technique. Three damage modes, namely, coating damage, corrosion and crack propagation, were determined using AE parameters analysis, that is the distribution of amplitude and peak frequency.
