High Performance YBCO Films
Abstract
A number of attempts were made to attach a metal handle consisting of Cu/Stainless 409/Cu composite to YBCO using a crystallizing lead-zinc-borate glass as bonding agent. A strong, well adhering bond was achieved to MgO and SrTiO3 as buffer layers on top of the YBCO. Unfortunately a substantial portion of the buffer layers and the YBCO appear to have been dissolved by the bonding glass. Experiments with thicker buffer layers and other buffer materials are underway. Initial results with Y2O3 as a buffer layer look very promising. A glass/metal handle attached to a YBCO/Y2O3 layer combination at 460 deg C showed good adherence and no apparent damage to the YBCO layer. This system is being evaluated further
