摘要：

Scale-up matters for ion-beam-assisted deposition (IBAD) method was surveyed on biaxially textured yttria-stabilized-zirconia (YSZ) buffer layer by using 66 cm x 6 cm square-shaped RF-discharged ion source. Textured YSZ films with the in-plane mosaic spread (Delta phi) of 9-15 were obtained in the growth area of 60 x 8 cm(2) by optimizing the beam collimation for the assisting Ar ions. 5.5 in long YSZ textured template layers were formed with 0.1 m/h by IBAD on Ni-Cr alloy tapes with the Delta phi of 12-13 degrees in whole length. The Delta phi of 10.8 degrees was obtained in a short tape moved with 0.3 m/h. Y-123 films were deposited by PLD on the YSZ templates with tape shifting speed of 1.0 m/h. I-c of 84.0 Angstrom and J(c) of 0.76 MA/cm(2) were obtained at 77 K, 0 T in the length of 1.0 m with Delta phi for the Y-123 film was 7 degrees. (C) 2001 Elsevier Science B.V. All rights reserved.
