Abstract

Steam oxidation test was carried out at 800 °C for 2000 h on nine plasma sprayed coatings on gamma-prime (γ’) strengthened Haynes® 282® Ni-based alloy. The lowest oxidation kinetics and extensive reduction in internal oxidation process was observed in the sample coated with nano CeO2 with no bond coat. This is due to the oxygen deficiency in CeOx that facilitates the inward movement of oxygen arising from the presence of Ce3+ oxidation state and ensures the quick formation of protective, impermeable and adherent layer of Cr2O3.
