Evaluation of the Protection Effect on Copper with Different Sacrificial Anodes

Abstract:

Sacrificial anodes performance of three iron alloys was measured by constant current test, The protection effects of iron alloys, zinc alloy and aluminum alloy sacrificial anodes on copper tube were compared and analysed by polarization test. The results show that all three iron alloys appearing well sacrificial anodes performance, with steady working potential, high practical electric capacity and current efficiency, the corrosion is uniform and the corrosion products fall easily. Iron alloys are more suitable for application on the cathodic protection of copper tube due to their more suitable driving voltage and coulpling current compared with zinc alloy and aluminum alloy.
