Atmospheric corrosion monitoring of metals using electrochemical impedance

摘要

Atmospheric corrosion is greatly influenced by various environmental factors such as temperature, relative humidity and airborne sea salt. It is necessary to examine in detail the relationship between environmental factors and corrosion behaviour, in order to clarify the atmospheric corrosion mechanism. And then, the corrosion mechanism can lead to an appropriate method for corrosion lifetime prediction. In this study, corrosion monitoring was conducted using concentric ring type corrosion sensor under the environment controlling some parameters.
