TL;DR: In this paper, the role of chloride ions in metastable pitting of A516-70 carbon steel was studied based on the statistical analysis of recorded current and potential noise, and it was shown that the amplitude and occurrence frequency of current/potential transients, indicating the initiation of metastable pits, increase with the concentration of chloride ion.

TL;DR: In this article, the relationship between the spectral parameters (rolloff slope and rolloff frequency) in the frequency domain and the transient variables in the time domain were analyzed and the influence of corrosion types on noise spectra was considered.

TL;DR: In this article, the potential and current fluctuations of A516 carbon steel were monitored in a chloride solution and different noise patterns were observed during the incubation and initiation periods of pitting.

TL;DR: In this paper, the potential and current of A516-70 carbon steel were analyzed in the time domain for pitting corrosion in 0.5 M NaHCO3 or 0.1% NaNO2 solutions containing NaCl at various concentrations.

TL;DR: In this article, the current transients during metastable pitting of A516-70 carbon steel in bicarbonate-chloride solutions were monitored and statistically analyzed, and two experimental approaches were used for this purpose: potentiostatic control and galvanic coupling.
