Abstract

The destabilization of zirconia thermal barriers has been monitored by directly exposing thin films of ZrO2 (+Y2O3) to V2O5 vapor. The growth of YVO4 and the transformation of cubic ZrO2 (+Y2O3) into tetragonal and/or monoclinic ZrO2 polymorphs are monitored by selected-area diffraction and energy-dispersive x-ray spectroscopy in the transmission electron microscope. The structure of a special YVO4 - ZrO2 (+Y2O3) interface is discussed.
