Laser Flash is considered the standard technique for measuring the thermal diffusivity of solids. The interaction between TBC and the laser energy is studied because very low thermal effusivity and thermal diffusivity of TBC can produce very high temperature increase on the surface and temperature gradient within the sample. In such a case, microstructural modifications of TBC can be generated. In this work, such phenomena are studied experimentally on free standing TBC samples.

Abstract
Laser Flash is considered the standard technique for measuring the thermal diffusivity of solids. The interaction between TBC and the laser energy is studied because very low thermal effusivity and thermal diffusivity of TBC can produce very high temperature increase on the surface and temperature gradient within the sample. In such a case, microstructural modifications of TBC can be generated. In this work, such phenomena are studied experimentally on free standing TBC samples.File in questo prodotto:
