Paper Abstract
A description of preliminary experimental work, in which thickness of ceramic coatings is measured using pulse echo thermal wave imaging, is presented. The thermal wave measurement technique uses the time (relative to flash heating) at which the peak slope of the contrast curve occurs to determine the thickness of the coating layer, based on reflection of the thermal wave from the coating/substrate interface. Thermal wave thickness measurements are compared to measurements made (destructively) with a drill micrometer. Repeatability and precision of measurements are discussed.
