Abstract

High performance long-length coated conductors
fabricated using various techniques have attracted a lot of interest
recently. In this work, a reel-to-reel design for depositing
double-sided coatings on long-length flexible metallic tapes via a
chemical solution method is proposed and realized. The major
achievement of the design is to combine the dip coating and
drying processes in order to overcome the technical difficulties of
dealing with the wet films on both sides of the tape. We report
the successful application of the design to fabricate a one-meterlong
double side coated CeO2/Ni − 5at%W template. The CeO2
films on both sides exhibit a dense, crack-free morphology, and
a high fraction of cube texture on the surface. Homogeneity
studies on global texture over the length also reveal that the
average full width at half maximum values of the in-plane and
out-of-plane orientation on the CeO2 layer are 7.2◦ and 5.8◦
with standard deviation of 0.26◦ and 0.34◦, respectively, being
indicative of the high quality epitaxial growth of the films prepared
in the continuous manner. An all chemical solution derived
YBCOLow−TFA/Ce0.9La0.1O2/Gd2Zr2O7/CeO2 structure is obtained
on a short sample, demonstrating the possibility of producing
long-length texture templates for coated conductors by this low
cost deposition route.
