Notes:
The effect of NiCoCrAlYx-ZrO2 (1-x) interlayer on the residual stresses in theZrO2/NiCoCrAlY thermal barrier coating due to thermal cycling was analyzed using the finiteelement method. Modeling results showed that the magnitude and distribution of the residualstresses in the coating were strongly influenced by the material combination characterized by thevalue of x and the thickness of interlayer. The maximum tensile stresses at the different regions (i.e.coating/substrate interface, coating surface, et al.) as functions of the material combination and thethickness of the interlayer were obtained. The physical meaning of the above results was alsodiscussed
