帯状陽極の電位分布計算式と陽極周囲の絶縁処理の検討

抄録

To extend the cathodically protected area with impressed current, strip-type anode and the coating around the anode has been examined through mathematical calculation and a simulation tank experiment. The following main trends have been observed.
1) A method for calculating the potential distribution is presented and the formula obtained has been shown reasonable by the experiment.
2) Steel surface coated with an insulation coating around the anode gives the equivalent effect as an enlarged anode having the same area.
3) As for a coating material around the anode, neoprene rubber lining of 1mm thickness can be adopted.
