    Abstract

    A review is presented of the use of impedance techniques in corrosion science. Emphasis is placed on defining the type of data that is required in corrosion studies, and then comparing different methods for generating the required information by electrochemical impedance methods. The performance characteristics of the various techniques, including cost, are critically compared to assist readers in selecting the most appropriate system for their needs.
