Abstract

Effective thermal conductivity is an important parameter for the design of porous ceramic coatings that are exposed to high temperatures. Pore shapes which change in relation with the coating parameters and coating method affect the effective thermal conductivity significantly. In this study the effective thermal conductivity of 8 wt % yttria stabilized ZrO2 coating deposited by air plasma spraying have been calculated by finite element method using digital images. The effects of pore shape on effective thermal conductivity have been discussed.
