Abstract

Ceria-yttria stabilized zirconia (CYSZ) coatings were prepared by air plasma-sprayed on the nickel alloy. The as-sprayed CYSZ coatings and heat-treated CYSZ coatings were characterized by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The XPS data indicated the coexistence of Ce ³⁺ , Ce ⁴⁺ , Y ³⁺ and Zr ⁴⁺ ions near the surface of the as-sprayed CYSZ coatings and the disappearance of Ce ³⁺ ions in the CYSZ coatings after thermal treatment at 1000 °C for 15 h. From the XRD patterns, the solid solution of CeO ₂ -Y ₂ O ₃ -ZrO ₂ formed in the CYSZ coatings because of the lack of any features from Y ₂ O ₃ and ZrO ₂ single phases. After thermal treatment, the main phases of all the samples were consistent with the characteristic peaks of cubic ZrO ₂ .
