Microstructural Characterization and Thermal Barrier Effects of Conventional and Nanostructured ZrO₂-7wt.%Y₂O₃ Thermal Barrier Coatings Deposited by Plasma Spraying

Abstract:

In this study, conventional and nanostructured MCrAlY/ZrO₂-7wt.%Y₂O₃ double-layer thermal barrier coatings (TBCs) were fabricated on TiAl base intermetallic alloy substrates by the plasma spraying technique. The microstructural characterization and thermal insulation capability of the two types of coatings were comparatively researched. The results show that the conventional ceramic coating has a typical lamellar stacking characteristic. However, the nanostructured coating exhibits a bimodal microstructure, which is composed of both fully melted regions and partially melted regions (remained nanoparticles). The nanostructured TBCs has higher thermal barrier effect than the traditional one. The temperature drops of the nanostructured TBCs at 1100 °C increases 53% compared with that of the conventional TBCs.
