Abstract :
Thick, partially yttria-stabilised zirconia coatings have been deposited by PECVD. Evolution of the morphology and phase composition has been studied as a function of the annealing temperature and duration (1100–1400°C, for up to 1000 h). The as-deposited columnar morphology is similar to EBPVD and in good agreement with the PVD structural zone models. Evolution of the phase composition follows the phase diagram. The overall thermal stability observed is encouraging for TBC applications.
