Abstract

Effects of solid solution treatment and rolling treatment on microstructure and electrochemical properties of Al-Ga-Mg-Mn-Bi anode alloy were investigated by means of SEM and electrochemical measurements. The results show that after solid solution treatment the microstructure segregation of the as-cast alloy was reduced, the hydrogen evolution was restrained, the corrosion resistance was increased. The open circuit potential moves towards negative after solid solution treatment. Rolling treatment had little impact on the alloy. The effects of solid solution treatment were superior to rolling treatment.
