Electrochemical Frequency Modulation: A New Electrochemical Technique for Online Corrosion Monitoring
TLDR
In this paper, a potential perturbation signal by one or more sine waves will generate current responses at more frequencies than the corresponding sine wave wave wave frequencies, which is a nonlinear electrochemical phenomenon.Abstract:
Since a corrosion process is a nonlinear electrochemical phenomenon, a potential perturbation signal by one or more sine waves will generate current responses at more frequencies than the ...read more

Testing validity of the Tafel extrapolation method for monitoring corrosion of cold rolled steel in HCl solutions – Experimental and theoretical studies
TL;DR: In this article, the protection influence of glycine (Gly) and a one of its derivatives, namely 2-(bis(2-aminoethyl)amino) acetic acid, designated here as GlyD; where GlyD stands for “glycine derivative”, against cold rolled steel (CRS) corrosion was studied in aerated stagnant 1.0 M HCl solutions at 25°C.

Mechanism and Phenomenology of Organic Inhibitors
TL;DR: In this article, the authors define corrosion inhibitors as substances that inhibit one or more of the partial processes of the corrosion process as a whole, and define them as substances whose presence is not essential to the occurrence of an electrochemical process, but leads to a retardation of this process by modifying the surface state of the metallic material.
