Galvanic aspects of aluminum sacrificial anode alloys in artificial seawater were investigated. Specifically, two mercury-bearing alloys and one tin-bearing alloy were studied. The polarization behavior of the aluminum sacrificial anode alloys coupled to HY-80 steel is discussed. Current versus time curves were obtained for aluminumsteel galvanic couples immersed in artificial seawater for specific intervals. Scanning electron microscopy was used to characterize the anode dissolution patterns and the corrosion mechanisms. A correlation is made between the dissolution morphologies exhibited by each anode alloy and the polarization and galvanic current data. Author
