Technical Operations Support (TOPS) II. Delivery Order 0007: Thermal Barrier Coatings

Abstract

This work formed the second part of an investigation into the use of Gd203 as an alternative stabilizer for Zr02-based thermal barrier coating (TBC) materials. The current state-of-the-art TBC material, Y203-stablized Zr02 (3.5-4 mole percent y203), referred to as YSZ, suffers from limited durability at use temperature above 100-1200 deg C. Our previous work investigated the influence of Gd203 concentration on the sintering and phase stability of conventional Zr02 powders. In this work, the effect of Gd203 concentration (420mo1%) on the sintering and phase transformation of plasma-sprayed Zr02 powders was investigated and the data were compared with those for YSZ.
