Abstract
Surface quality is an important factor that exerts a profound influence on both the extent and severity of damage due to corrosion that is experienced by an aircraft structure. In this study, a quantitative method was used to determine surface quality and the roughness of the surface was analyzed by scanning selected specimens of the chosen aluminum (Al) alloy with the aid of a scanner. Accelerated corrosion experiments on the chosen aluminum alloy, namely, 2A12, were performed in the laboratory air environment to analyze the influence of surface quality on both the initiation and growth of damage due to pitting corrosion. Results of the experiments revealed that, during the early stages of corrosion, a rough surface is more susceptible to the initiation and onset of corrosion by pitting and has a higher resultant corrosion rate. The corrosion rate gradually increases with time. With increased exposure to an aggressive environment, the influence of surface quality on environment-induced degradation, or corrosion, was found to disappear.
