Abstract
Axisymmetric explosive compaction with a shock-wave pressure of 2 GPa was used to obtain low-resistance Ag/YBCO (YBa2Cu3O7-x) contacts. Meas urements were made of compressive strength at 300 K and microhardness and electrical resistivity within the temperature interval 300-77 K fo r annealed specimens of Ag/YBCO. Ultimate compressive strength was 0.1 2 GPa. The microhardness of the ceramic near the Ag/YBCO interface was 3.1 GPa. Contact resistance at the temperature of liquid nitrogen < 1 .10(-8) Ohm . cm(2) (contact area similar to cm(2)).
