| Objective A new type of sacrificial anode was designed to meet the protection current demand at different times of marine engineering steel structures and achieve the purpose of saving the amount of sacrificial anode. Methods By changing the area to weight ratios of the conventional anode, the same area and quality of conventional anode and new type anode were designed, respectively, and the comparative tests of cathodic protection in static seawater were carried out. Results One new type of anode, saving nearly 50% by mass, realized the similar current outputs with the same area of conventional anode. Another new type of anode, owning similar quality with the conventional anode, was increased nearly 70% of the surface area, and achieved the current outputs increasing 18% at the initial stage and 14% throughout the test, and the rapid polarization of the protected specimens. Conclusion By increasing the area to weight ratios of conventional anode, it is feasible to reduce the anode-to-electrolyte resistance, and then increase the current outputs. |
