The results show that there exist different corrosion types of the alloy in 3.5% NaCl solution with immersion time. At the initial stage of immersion, pitting predominate the corrosion around precipitates. The major precipitates of the alloy are MgZn2 and Al6Mn particles. The corrosion potential of the bulk MgZn2 alloy is negative with respect to that of the alpha-Al and the bulk Al6Mn alloy, so the MgZn2 precipitate can act as activation centre, make the aluminum oxide film breakdown and cause the pitting corrosion. In the late stage, it turns out to be a uniform corrosion due to the control of dissolution precipitation of In and Zn ions. (C) 2010 Elsevier B.V. All rights reserved.

Microstructures and electrochemical properties of the alloys were investigated. The results show that the optimal microstructures and electrochemical properties are obtained in Al-5Zn-0.03In-1Mg-0.05Ti-0.5La alloy. The main precipitate phase is Al2LaZn2 particles. The excellent electrochemical properties of Al-5Zn-0.03In-1Mg-0.05Ti-0.5La alloy is mainly attributed to fine grains and grain boundaries containing fine Al2LaZn2 precipitates. At the same time the fine grains can improve the non-uniform corrosion of Al-0.5Zn-0.03In-1Mg-0.05Ti alloy. (C) 2009 Elsevier Ltd. All rights reserved.
