Abstract
We investigated joint properties of REBCO (REBa2Cu 3O7-X, RE = rare earth element) coated conductors using a diffusion joint process. Two pieces of the coated conductor tapes with stabilizing silver layer on REBCO were overlapped in a face to face manner, which were pressurized and heat-treated at about 623-673 K in oxygen atmosphere. The joint resistance for YBCO tape was about 6.5 nΩ cm 2 at 77 K, on the other hand, that for GdBCO tape was about 37 nΩ cm2 which was higher than YBCO. From the results of both cross-sectional transmission electron microscope (TEM) and energy dispersive X-ray spectrometry (EDS) analysis, diffusion of Gd-element into Ag layer was observed for the joined sample of GdBCO tape, it is suggested to be a cause of higher joint resistance for GdBCO tape.
