摘要：
The effect of wetting time on localized corrosion of AA5083-H111 aluminum alloy in a dynamic seawater/air interface zone was investigated using electrochemical measurements, scanning electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. Longer wetting time resulted in a more serious localized corrosion degree and thus led to an uneven and incomplete corrosion product film. This was attributed to the presence of a thin electrolyte layer upon the alloy, restricting the repassivation of the corrosion pits.
