摘要

A CeO₂-dispersed nickel-aluminide coating was deposited by aluminizing a Ni-CeO₂ electroplating film with a Ni-Re interlayer pre-electroplated sequentially. The CeO₂-dispersed coating was exposed to dry and wet CO₂ gas at 650 °C for 1300 h. Internal oxidation and cavities were observed in the coating centralized around CeO₂ particles, which became more aggravated with the presence of H₂O in CO₂ gas. The activity of CeO₂/Ni₂Al₃ interface for CO₂ and H₂O dissociation and oxygen diffusion was studied by first-principle calculations. The effect of CeO₂ dispersion on the coating oxidation in dry and wet CO₂ gas was discussed.
