Fabrication of silver coated high temperature ceramic superconductor fiber with metal substrate

A method for manufacturing a copper and oxygen containing superconductor wire, which comprises the steps of:

• continuously drawing a metallic wire substrate through a processing zone at a predetermined tension;
• positioning a first solution in said zone around said wire substrate, said first solution containing ceramic superconductor particles, said first solution having a first electrode disposed therein;
• selectively establishing a voltage on said first electrode with respect to said metallic wire substrate to electrophoretically deposit said superconductor particles onto said wire substrate;
• sintering said superconductor particles;
• positioning a second solution in said zone around said superconductor grains, said second solution containing silver particles, said second solution having a second electrode disposed therein;
• selectively establishing a voltage on said second electrode with respect to said metallic wire substrate to electrophoretically deposit said silver particles onto said superconductor grains to form a silver coating thereon;
• sintering said silver;
• and
• covering said silver coating with a diffusion inhibiting layer.
