The Effect of Temperature and Dissolved Oxygen Concentration on the Electrochemical Behavior of Al-Zn-Inbased Anodes

摘要

The electrochemical behavior of three types of aluminium anode at different temperatures and dissolved oxygen concentrations was studied. Current efficiency tests were carried out. SEM and EDX were also conducted. The results suggest that when the temperature is much lower than room temperature, the dissolution morphologies of Al-Zn-In and Al-Zn-In-Cd anodes are non-uniform, and the Al-Zn-In-Mg-Ti anode exhibits uniform dissolution morphology. At low temperature, the dissolved oxygen concentration only affected the attack behavior of the Al-Zn-In and Al-Zn-In-Cd anodes but had little influence on the attack behavior of the Al-Zn-In-Mg-Ti anode.
