Abstract:

Corrosion is an industry-wide maintenance problem that has been rapidly expanding with the growth in aging structural components. The question now is whether to replace a structural component or to inspect and repair. Replacement can be performed on low-cost items such as land vehicles but inspection and repair have been the preferred route for high-cost items such as offshore platforms, aircraft, ships, and missiles. While the inspection and repair approach is justified, the reliability of certain nondestructive evaluation NDE inspections is questionable. Methods for detection of hidden corrosion, measurement of material degradation due to corrosion, and quantification of corrosion are not fully developed. The need for improving inspection methods is, however, accelerating with the increasing inventory and age of defense equipment and with the high cost of adding new equipment. This report is a survey of the NDE methods presently being used for detection and evaluation of corrosion.
