| Abstract: | An original process of superficial thermal treatment is described. This process has been successfully applied to partially stabilized yttria-zirconia coatings (ZrO2-Y2O3) to increase the lifetime of the thermal barriers. A thin superficial layer was melted, and morphological transformations were observed. A microstructural comparison between as-sprayed layers and thermally treated layers is presented. |
