The results showed that the current condition had a significant effect on the corrosion of 1050 Al-alloy. Both of the corrosion current density and mass loss rate of the sample increased gradually with the increment of applied current density.The corrosion behavior of 1050 Al-alloy in marine atmosphere was characterized in simulated electrification condition through the analysis of the structure and morphology of corrosion products.
