Studying the pitting corrosion of steel in the conditions of galvanostatic polarization by EIS technique.

This paper shows the main regularities of changes in the electrochemical behavior of surfaces when using the EIS technique. It is found that the EIS technique in the galvanostatic environment is an efficient tool to study the pitting corrosion process. Optimal equivalent electrical circuits are proposed, reflective of the surface condition at different stages pitting corrosion propagation. [ABSTRACT FROM AUTHOR]
