Laboratory investigation of microbiologically influenced corrosion of 2205 duplex stainless steel by marine Pseudomonas aeruginosa biofilm using electrochemical noise

Corrosion Science, 2018
The corrosion mechanism of a 2205 duplex stainless steel (DSS) in Pseudomonas aeruginosa inoculated medium was investigated using the information of electrochemical current noise (ECN) transients derived from Hilbert spectra and surface analysis. The pit

DETECTION OF CORROSION BY ANALYSIS OF ELECTROCHEMICAL NOISE

Fractals, 1994
Stochastic fluctuations of the corrosion potential and the current generated by corrosion reactions are known as electrochemical noise. These fluctuations can be measured in freely corroding systems, therefore the characteristics of electrochemical noise are influenced only by the type and rate of corrosion.

The measurement of corrosion using electrochemical noise

Corrosion Science, 1982
Abstract Amplitude spectra of low frequency electrochemical noise are presented which show a correlation between the rate and mode of corrosion attack and fluctuations of the corrosion potential. The results indicate the possibility of a non-perturbative electrochemical corrosion monitoring technique capable of detection of pitting and crevice attack.

Evaluation of a Polymeric Concrete by Electrochemical Noise

CORROSION 1998, 1998
Abstract Eletrochemical Noise (EN) and Electrochemical Impedance Spectroscopy (EIS) have been used as electrochemical tools, due to the high resistivity of the environment to determine at laboratory level the amount of protection against corrosion that a new polymeric concrete, developed by the Electrical Research Institute of Mexico ...

ASTM Standardization of Electrochemical Noise Measurement

1996
The increased utilization of electrochemical noise measurement in corrosion research and industrial process monitoring prompted the formation in 1991 of an ASTM Task Group within the G1 Corrosion of Metals Committee. The scope of the task group was to “develop standards that describe instruments and methods for making and analyzing electrochemical ...

Controled Potentiostatic Measurements of Electrochemical Noise

CORROSION 2000, 2000
Abstract A new controlled potentiostatic electrochemical noise (P-ECN) technique was developed to improve the correlation between current and potential noise. This technique enhances monitoring of both general and localized corrosion. P-ECN uses a standard one-working, three-electrode electrochemical cell where both current noise and ...

Fractal theory of electrochemical diffusion noise

Russian Journal of Electrochemistry, 2015
The stochastic analysis of the properties of equilibrium noise in an electrochemical ac circuit which corresponds to the electrochemical system with the diffusion control over the Faradaic process is accomplished. It is shown that adequate consideration of the Warburg impedance noise leads to the bifractal stochastic Langevin equation which involves ...
