Abstract  The effect of indium on the dissolution of aluminium sacrificial anode was studied. Results showed that the potential of Al-Zn-In anode shifted towards negative and its electrical efficiency descended with increasing amount of indium in alloy; indium segregated in such alloys; corrosion pits distributed uniformly on the whole surface of the anode, and the In-rich islands were discovered in these pits. U shaped curves of time versus the amount of indium dissolved were obtained. It is proposed that the In-rich segregated phase particles activate the dissolution process of aluminium sacrificial anode.
