| Abstract | |
The addition of silver in hypoeutectic Al-Si alloys have been demonstrated to have promising mechanical and electrical properties. However, the relationships between corrosion behavior and microstructure are yet to be determined for Al-Si(-Ag) alloys, which restricts their wider application. Therefore, this study evaluates the impact of Ag addition (0.1 and 2.0 wt%) on the microstructural pattern of the Al-5.0wt%Si alloy and explores the effect of the secondary dendrite arm spacings, lambda(2), and interdendritic phase distribution, on the corrosion properties. Among the three alloys, the Al-5.0wt%Si-0.1wt%Ag alloy exhibited the highest corrosion resistance and largest passivity intervals, in addition to having a high mechanical strength for smaller lambda(2). {[}GRAPHICS] .
