Summary: | 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-meter-long double side coated [Formula Omitted] template. The [Formula Omitted] 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 [Formula Omitted] layer are 7.2 [Formula Omitted] and 5.8[Formula Omitted] with standard deviation of 0.26[Formula Omitted] and 0.34[Formula Omitted], respectively, being indicative of the high quality epitaxial growth of the films prepared in the continuous manner. An all chemical solution derived [Formula Omitted] 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. |
