Abstract: Surface quality is one of the most important factors of corrosion damage in aircraft structure. In this paper, quantitative method was used for surface quality, the surface roughness was obtained by scanning the specimens with a scanner. Accelerated corrosion experiments of aluminum alloy 2A12 were performed in the laboratory to analyze the effect of surface quality on the occurrence and development of pitting corrosion. The results of the experiments show that in the initial stage of the corrosion, a rough surface is more susceptible to pitting corrosion and have a larger corrosion velocity. The corrosion velocity increases with time. With the extension of time, the effect of surface quality on the corrosion behavior tends to disappear.
