摘要: The corrosion of manufactured epoxy-coated reinforcing steel with intentional surface damage in a naturally aerated NaCl solution was investigated. progression as function exposure time studied electrochemical impedance spectroscopy (EIS). Impedance diagrams were roughly semicircular large apparent constant. Integrated rates from nominal charge-transfer resistance evaluations reasonable agreement direct metallographic measurements metal loss at the end exposure. results interpreted transmission-line EIS model, proposing that cathodic reactions took place external, semiconductive products.
