Abstract
A system for nondestructive analysis of barrier coatings on electrically conductive materials includes imposition of a controlled known heat load to a localized area of the coating and measuring electrical conductivity of the underlying material at or near the localized area of the coating. The electrical conductivity of the material is affected by changes in temperature related to thermal conduction into the material through the coating. Thermal resistance of the coating and defects between the coating and the material can therefore be detected.
