CORROSION/ANTICORROSION STATE EVALUATION METHOD, POTENTIAL MEASURING INSTRUMENT, AND REFERENCE ELECTRODE

摘要

The corrosion/anticorrosion state of a structure (A) in an external electrolyte is accurately evaluated by means of a reference electrode (3). A pseudo member (1) of the structure (A) is provided near the structure (A), with a specific surface (12) in electrical contact with the external electrolyte (6). The electrolytic solution (19) of the reference electrode (3) is brought into electrical contact with the external electrolyte (6) at a position near the specific surface (12), and the potential of the pseudo member (1) with reference to that of the reference electrode is measured. The corrosion/anticorrosion state of the structure (A) is evaluated on the basis of the measured potential.
