Abstract: Corrosion mechanism and morphology changes of aluminum alloy in model solution corresponding sea water containing gluconates and zinc ions were investigated by immersion corrosion tests with surface analysis. Surface and cross-sectional SEM results showed that zinc ions suppress the morphology changes of aluminum alloy in the solution containing gluconates. XPS analyses indicated that gluconates in the solutions adsorb on the oxide films of aluminum alloy and protective films of the adsorbed gluconates would prevent the penetration of chloride ions to the aluminum alloy. The XPS results also suggest that zinc ions in the solutions bond to the oxide film of aluminum alloy and zinc ions enhance the corrosion inhibition ability of the protective films of gluconates for aluminum alloy in model sea water.
