PROBLEM TO BE SOLVED: To provide a method of electric corrosion protection in the atmosphere for preventing the corrosion of painted surface with certainty. SOLUTION: In the method for the electric corrosion protection of a structure in the atmosphere, an electrode is disposed via an insulating material on the surface of a single-layer or multilayered film formed on the surface of an object of corrosion protection made of metal and an electric current is applied from an external power source using the above electrode as a positive electrode and the object of corrosion protection as a negative electrode; or the external power source is not used and a sacrificial anode is disposed as the electrode and this sacrificial anode is electrically connected to the object of corrosion protection. In both cases, the film having a photocatalytic action in the outermost surface layer is used. |
