Nondestructive mapping of corrosion of steel beneath paint coating by synchrotron X-ray absorption spectroscopy

Abstract

An application of synchrotron X-ray absorption spectroscopy (XAS) for a nondestructive evaluation of corrosion of steel beneath an organic paint coating is discussed. The XAS technique is applied to map out the corrosion beneath paint coating for the nondestructive evaluation, and to identify chemical species of corrosion products.
