摘要：
MOCVD process development utilized a cold wall reactor with liquid delivery of a metal-organic precursor solution to deposit yttria-stabilized zirconia. At high temperature (> 950 degrees C) the deposition process is transport limited and the rate is ultimately controlled by the solubility of the selected precursor in the selected solvent. Proposed, thick thermal barrier coatings with a columnar structure have been successfully deposited on developmental FeCrAlY material and resistance to spallation during thermal cycling in initial testing has been demonstrated on preoxidized surfaces.
