摘 要:Thermal barrier coatings(TBCs)have been widely applied to protect metallic components in gas turbines or aero engine against the high temperatures. In the recent decade,considerable numerical models have been built up to present the thermal spray process.However,much less work has focused on the Pre-diction of the insulation temperature to the TBCs,which is an important parameter to affect the perform-ance of the TBCs during their applications.In the present study,a 3D finite element simulation has been carried out to predict the heat insulation behavior of the 6%~8% yittria partially stabilized zirconia coat-ings based on a two-layer model.Furthermore,such factors as the heat transfer mode,the thickness of the coating,properties of the coating as well as the microstructure of the coating have been ntimerically inves-tigated.The significance of the finding is also discussed.
