Recently, the electrochemical noise analysis is received attention as a corrosion monitoring technique for chemical plants, including salt production facilities. In this article, a concept of electrochemical noise analysis as an approach for predicting the generation of localized corrosion was briefly reviewed. The electrochemical noise is a transient current or a potential fluctuation generated by the current. The transient current is generated with an initiation-repassivation cycle of metastable pits or small cracks. A generation mechanisms of the transient current, a method for measuring the electrochemical noise, and a way to monitor the risk of developing pitting and stress corrosion cracking from the analytical results were described.
