Electrochemical noise for corrosion monitoring

Abstract Electrochemical noise (EN) is a generic term used to describe the fluctuations in potential and current that occur on a corroding electrode. EN is produced by the processes causing the corrosion (or other electrochemical reactions), and it has been a hope of corrosion researchers that its interpretation would provide an understanding of the corrosion process that cannot be obtained by other means. So far, this hope has not been completely realized, but some progress has been made, and the method has been used for corrosion monitoring. This chapter will review the development of our current understanding of EN and the methods that have been used in corrosion monitoring.
