Abstract

Nonvacuum electrodeposition was used to prepare biaxially textured CeO2 and Sm-doped CeO2 coatings on Ni-W substrates. The samples were characterized by X-ray diffraction (including Θ/2Θ, pole figures, omega scans, and phi scans), atomic force microscopy, and Auger electron spectroscopy (AES). Pole-figure scans show that electrodeposited CeO2 and Sm-doped CeO2 on textured Ni-W (3 at.%) is cube textured. Full-width at half-maximum values of thew scan andf scan of the electrodeposited layers were better than those of the Ni-W base substrates, indicating improved biaxial texturing of the electrodeposited layers. AES analysis of the YBCO/CeO2/YSZ/ED-CeO2/Ni-W revealed that Ni interdiffusion was completely stopped at the first electrodeposited CeO2 layer.
