Article Preview

The solubility and cathodic protection performance of Al-Zn-In-Mg-Ga-Mn sacrificial anode in natural corrosion and self-discharge experiment was studied using electrochemistry impedance spectrum technology, weight-loss measurement and SEM. The results show that the corrosion rate of 7A52 was decreased under the protection of sacrificial anodes in the self-discharge experiment, and sacrificial anodes dissolved uniformity due to the effect of active location, the corrosion products are easy to shed. Only location corrosion occurs on the sacrificial anode’s surface which is influenced by corrosion products and oxide film in natural corrosion experiment.
