In this study, Electrochemical Noise (EN) was measured to understand the electrochemical behavior of galvanized and weathering steels in mortar. The relationships between the corrosion form based on wavelet analysis of EN and the observation of the surface film failure and corrosion product formation were investigated. Every steel showed a localized corrosion tendency in the EN analysis. This is due to the corrosion concentration at the film loss locations. Although the rate of film loss varies among the steels, clarifying the conditions that lead to film breakage, which in turn initiates corrosion, is necessary.
