SURFACE COATING INSPECTION USING WATER SPRAYING AND NUMERICAL MODELING

摘要

Described herein are methods and techniques for performing nondestructive flash thermographic evaluation of a surface coating with the aid of a liquid agent. The liquid agent is applied to a surface coating to be evaluated. The liquid agent has a high wetting affinity for the material of the surface coating and can be easily removed from the coating if, for example, additional layers of the coating need to be applied after the evaluation is performed. Also described herein are systems, methods, and computer-readable media for generating and applying a numerical model having a log-normal flash response distribution to experimental flash thermographic data to determine one or more parameters/material properties of the surface coating.
