Abstract

The earliest stages of the corrosion of ceramic therma-barrier coatings were analyzed during a model transmission electron microscope experiment designed to simulate the degradation of Y2O3-stabilized ZrO2 in the presence of V2O5. Thin films of Y2O3-stabilized ZrO2, previously prepared for examination in the transmission electron microscope, were exposed to the vapor emitted by a small quantity of V2O5 at 810-950°C. Morphological, chemical and structural transformations of the Y2O3-stabilized material were then characterized V2O5 reacts preferentially with Y2O3 to form YVO4 and ZrO2-enriched phases which possess inferior thermal and mechanical properties. The growth of YVO4 was monitored and a special orientation relation between Y2O3-stabilized ZrO2 and YVO4 is discussed. © 1989.
