Study on Performance of Al-Zn-In-Mg-Ti Sacrificial Anode
The dissolve behavior and cathode protection performance of Al-Zn-In-Mg-Ti anode was studied by electrochemistry impedance spectrum technology, weight-loss measurement and SEM in natural corrosion and self-discharge experiment. The results show that the 7A52 corrosion rate was decreased at a certain extent which under the protection of sacrifice anode in the self-discharge experiment, but the protection was inefficient and sacrificial anode corrosion products fell off uneasily. Natural corrosion sacrifice anode surface influenced by the corrosion product and the oxide film, the number of active pot was reduced with the progress of experiment.
