DETECTING CORROSION IN STEEL PRODUCTS BY DYNAMIC INFRARED THERMOGRAPHY

This article describes an algorithm for quantitative determination of material losses in the corrosion of metal products. The determination is made on the basis of thermographic inspection. Analysis of empirical data for a steel plate 3 mm thick shelved that an acceptable level of accuracy in flaw detection is achieved when more than 20% of the overall thickness of the wall has corroded.
