CORROSION PREVENTION STRUCTURE OF METALLIC STRUCTURE, CORROSION PREVENTION METHOD AND CORROSION-PREVENTING BODY

摘要

PROBLEM TO BE SOLVED: To provide the corrosion prevention structure of a metallic structure with which corrosion prevention stable over a long period of time can easily and securely be applied even to a metallic structure having complicated structure.

SOLUTION: In the corrosion prevention structure of the metallic structure, the surface of the metallic structure 2 to be subjected to corrosion prevention is provided with a liquid-permeable layer 3, further, the outside of the liquid-permeable layer 3 is provided with a corrosion prevention layer 4, wherein the corrosion prevention layer 4 consists of a composite containing: a galvanic-anodic metal with a potential lower than that of the metal composing the metallic structure 2 to be subjected to corrosion prevention; and an electrolyte forming material. The outside of the corrosion prevention layer 4 is preferably provided with a covering layer 6. The corrosion prevention structure is preferably provided with an electrically conductive material 5 arranged in such a manner that one end part thereof is joined to the metallic structure 2 to be subjected to corrosion prevention and the other end part reaches the corrosion prevention layer 4.
