Effect of Quenching on the Corrosion Morphology of Al-Zn-Sn-Ga Anode Alloy

Abstract:

In this paper, the Al-Zn-Sn-Ga anode alloy was quenched from 460 °C. The influences of corrosion time and different microstructure of the alloy on its corrosion morphology were investigated to clarify the effect of quenching on the corrosion morphology of the alloy. The inhomogeneous composition in the as-cast alloy directly caused various corrosion potential in the alloy and that the driving force of corrosion was different. Lots of circular corrosion pits and basic uniform composition were observed in the quenching sample. The results reveal that the corrosion morphology of the anode alloy is affected by quenching treatment employed.
