Abstract

The critical currents of sintered YBa2Cu3O6.5+δ were measured as the variables with the corrosive time in
the humid air. The corrosive process was studied by means of the current changes. Ag coating on the textured YBCO and polytetrafluoroethylene (PTFE) coating on the sintered YBCO were prepared. The critical
current densities of different YBCO samples with and without coatings were compared. Both Ag coating
and PTFE coating can well protect YBCO from moisture and CO2.
