The type I pitting corrosion occurs in the freshwater of relatively high concentration of bicarbonate and the type II in the freshwater of relatively high concentration of sulfate. The aim of this study is to develop an electrochemical test method by which one can reproduce the type I and type II pitting corrosion in artificially synthetic solution in relatively short period. For the type I pitting corrosion, the test solution contains 100mg/L HCO3 -, 10mg/L SO4 2- and 26.6mg/L Cl- and for the type II, the solution contains 10mg/L HCO3 -, 50mg/L SO4 2- and 26.6mg/L Cl-. In the test solutions, immersion of copper tube was carried out for two days, followed by a potentiostatic polarization for 4 weeks at a potential nobler by 100mV than the corrosion potential. The above procedure was found to relatively well reproduce the patinas and pits appearing in the real type I and type II pitting corrosion.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"境
