Study on the Splash Zone Corrosion Protection of Carbon Steel by Sacrificial Anode

The reason that sacrificial anode can not work properly in the area of splashed zone is that there is no stable electrolytes around the metalwork to enable the anode to function. In this paper the water absorbing capacity of materials was evaluated in order to select a suitable material that can be applied to the splash zone to form a stable electrolyte layer. Then the effect of sacrificial anode on the splash zone corrosion was studied by field exposure and cyclic wet and dry method.
