| Abstract: | The thermal conductivity and thermal diffusivity of ZrO2 coatings were studied using arc-photothermal evaluation technique in which the sample was heated at front surface and detected at back surface, and finite-difference thermal flow model was applied. The values of thermal conductivity and thermal diffusivity of ZrO2 are ｋ＝０．００６９Ｊ／ｃｍ·Ｋ·ｓ and α＝０．００２８ｃｍ2／ｓ, respectively. It is shown that, first, the finite-difference thermal flow model is an available and useful method for the multilayer coating system, and, second, the arc photothermal evaluation technique has low cost of equipment, and more simple and convenient measurement. |
