Original Abstract

In this work, critical locations in plasma-sprayed thermal barrier coatings are identified based on finite element calculations of residual cooling stresses that took into account waviness of the bond coat surface. The results are compared to microscopic observations of oxidized and thermally cycled specimens with conventional (CoNiCrAlY + Y2O3-ZrO2) and novel (CoNiCrAlY + ZrO2-Al2O3-SiO2) coatings.
