T1  - Thermal diffusivity measurements on two-layered and three-layered systems with the laser-flash method
JF  - High Temperatures – High Pressures
N2  - A research effort is reported in which the thermal diffusivity of coatings on substrate materials has been determined. The measurements were performed with a conventional laser-flash apparatus with rear-side detection of the temperature response with an infrared detector. In the evaluation of the data the theoretica! curve is fitted to the complete recorded temperature–time curve, instead of just using the t1/2 point. It is also demonstrated how to include the influence of a thermal contact resistance between the two layers in the evaluation. The paper presents measurements on two-layered and three-layered heat-barrier systems consisting of ZrO, and Ni CrA| Y on nickel.
