Corrosion detection and monitoring are essential diagnostic and prognostic means for preserving material "health" and reducing life-cycle cost of industrial infrastructures, weapon systems, ships, aircraft, ground vehicles, pipelines etc. This paper provides a literature review of technologies currently under use or in the development stage, and promises a non-destructive approach to corrosion measurement, detection and monitoring. A major portion of the iifecycle cost for all
platforms and infrastructures is due to labor hours spent in finding the problem and then fixing them with either a major overhaul or extensive part replacement. Knowing where the problem is early on could save up to 30% total ownership cost. It is estimated that U.S. spends over $300 billion in corrosion costs annually. This review is by no means exhaustive, but is comprehensive enough in describing major technology areas such as visual, fiber-optic, ultrasonic, acoustic, radiographic,
thermal imaging, electrochemical, chemical, fluorescence and miscellaneous other techniques. It provides numerous references, which would be very helpful in finding the details of each technique described.
