Much has been published describing various electrochemical techniques for evaluating resistance to localized corrosion.1-13  However, almost all the literature relates to carefully controlled research and product development work, while little has been published discussing the use of electrochemical techniques to solve localized corrosion problems in industrial settings. Corrosion engineers involved in production support might infer from this lack of information that, for a variety of reasons, electrochemical techniques are basically unsuitable for use in the production support function. This paper attempts to show otherwise, by presenting several case histories which illustrate how several simple electrochemical test techniques were used to solve industrial corrosion problems. The cases cited show that electrochemical test techniques not only perform adequately in the production support function, but that they can be superior to coupon-type tests by virtue of their speed, and promotion of understanding of the corrosion processes at work.
