Electrochemical noise technique for corrosion assessment - a review

Abstract

This review details the electrochemical noise technique as applicable to corrosion assessment with emphasis on the fundamental principles, theoretical aspects, data analysis and applications. The use of this technique in understanding the mechanistic aspects of corrosion and corrosion monitoring has been discussed. The important applications of this technique in corrosion processes like uniform corrosion, localized corrosion (pitting, crevice corrosion and stress corrosion cracking), and evaluation of coatings are highligted. Miscellaneous applications are also explained.
