Abstract:
The corrosive experiments of YBCO were conducted in the steam at different temperatures. The relationship between the critical current and the corrosive time at the same temperature was measured. The corrosion rate was also calculated. The textured YBCO superconductor was coated by sintering Ag plating method. Another coating method with polytetrafluoroethylene (PTFE) and low temperature resin was studied for the sintered YBCO superconductors as the protect layer. The above two kinds of coating methods can be used to meet the desire of the protection for YBCO superconductor and its thin film device.
