Non-vacuum electrodeposition (ED) was used to prepare a biaxially textured Gd{sub 2}Zr{sub 2}O{sub 7} (GZO) and GZO/Gd{sub 2}O{sub 3} (GO) buffer layer on a Ni-W substrate. The YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) superconductor was deposited by pulsed-laser deposition (PLD) on a simplified ED-GZO and ED-GZO/ED-GO buffer layer. The buffer layers and YBCO superconductor were characterized by X-ray diffraction (including {theta}/2{theta}, pole figure, omega scans, and phi scans) and atomic force microscopy. Full-width at half maximum values of the omega ({omega}) and phi ({phi}) scans of the electrodeposited GZO and GZO/GO layer were better than those of the Ni-W base substrate. At 77 K and a self-magnetic field, the critical current density of PLD YBCO on the electrodeposited-based buffer layer was 3.3 x 10{sup 6} A/cm{sup 2}, using the field criterion of 1 {micro}V/cm.
