PROBLEM TO BE SOLVED: To provide an anticorrosion method and an anticorrosion device which are capable of easily implementing anticorrosion treatment to a structure in which corrosion occurred.SOLUTION: A water-absorbing sheet 2 which is made of an insulator and absorbs external moisture W and a sacrificial anode material 1 which is made of a less noble material to a member to be protected from corrosion S and in which a plurality of communication holes communicating from outside to the water-absorbing sheet 2 are formed are arranged for the member to be protected from corrosion S in which a surface is oxidized and a corrosion layer R is formed so as to sandwich the water-absorbing sheet 2 between the corrosion layer R and the sacrificial anode material 1, and a pair of terminals severally arranged for the member to be protected from corrosion S and the sacrificial anode material 1 are electrically connected, external moisture W is supplied to the water-absorbing sheet 2 via the plurality of communication holes, the moisture W absorbed by the water-absorbing sheet 2 forms a corrosion circuit T, and the corrosion layer R is reduced by electrons conducting in the corrosion circuit T from the sacrificial anode material 1 to the member to be protected from corrosion S and converted into a conversion layer B.SELECTED DRAWING: Figure 1 |
