Sensitivity of thermal-wave interferometry to thermal properties of coatings: application to thermal barrier coatings
Thermal-wave interferometry is used as a means for measuring the thermal properties of coatings. The characterization procedure is influenced by the magnitude of the signal-to-noise ratio and also by the amount of experimental data available. These issues are analyzed using a sensitivity study, and...

| Summary: | Thermal-wave interferometry is used as a means for measuring the thermal properties of coatings. The characterization procedure is influenced by the magnitude of the signal-to-noise ratio and also by the amount of experimental data available. These issues are analyzed using a sensitivity study, and the factors that determine the accuracy of the technique are described. Results obtained from experiments on plasma-sprayed yttrium-stabilized zirconia coatings illustrate the accuracy and the limitations of TWI for the evaluation of the thermal properties. (Author) |
