Abstract

Optical generation and optical detection of thermal waves are used to determine the thermal properties of three different oxide coatings on stainless steel substrates at temperatures up to 1173 K. The thermal diffusivities α and thermal conductivities κ strongly depend on the method of preparation as well as on the environmental conditions during deposition. Our experimental values for α and κ are generally lower than handbook data for bulk specimens of the same materials.
