Abstract : The objectives of the program were: Fabricate, by arc plasma spraying, test specimens using specific mixtures of Hastelloy X and zirconium dioxide (Hx-ZrO2); Determine mechanical properties of the Hx-ZrO2 specimens in both the as-sprayed condition and after exposure to high temperature thermal environments for times up to 1000 hrs; and Evaluate metallographically the test samples to correlate changes in microstructural characteristics with changes in tested mechanical properties.
