Abstract

Diffusion joint processes using Ag stabilizing layer for YBCO tape were performed in varied parameter such as temperature, time duration, cooling procedure and conditions of surface for Ag stabilizing layer to optimize for joint condition. We succeeded in developing a brief process with which low resistance below 5 × 10 -13 Ω m 2 at the joint without any degradation of I c was achieved by polishing surface of Ag stabilizing layer and quenching procedure. The polishing is effective in reducing joint time and temperature. The mechanism was discussed for the decrease in I c after joint held at 873 K.
