The Research Progress of Aluminum Alloy Corrosion in Marine Atmosphere

Abstract:

It is very important to study on the corrosion of aluminum in marine atmospheric environment, because aluminum alloy structure of weapon equipment usually serves in marine atmospheric environment. On the basis of marine atmospheric environment corrosion features, the paper summarizes the influence of marine atmospheric environment influencing factors (e.g., Relative Humidity, Concentration of cl^-, Alternate Drying-Wetting, Rainfall) on corrosion rule and corrosion rate of aluminum alloy, and analyses the mechanism of pitting, inter-granular corrosion and denudation. Then the natural environment exposure test and accelerated test were compared. Finally, the key research direction in the field of aluminum alloy corrosion in marine atmosphere was pointed out.
