Abstract
A system and method for mechanically forming a ceramic superconductor product. A system for making the ceramic superconductor includes a metallic channel portion having a cross section for receiving a ceramic superconductor powder, a roll to mechanically reduce the channel cross section and included superconductor powder and a cap portion welded to the channel portion using a localized high energy source. The assembled bar is then mechanically reduced to form a tape or wire end product.
Claims13
A system for mechanically forming a ceramic superconductor product, comprising:
- a metallic channel portion having a cross section for receiving a ceramic superconductor powder;
- roll means for mechanically compacting said ceramic superconductor powder within said channel portion, said roll means having a complementary cross section matingly receivable by said channel portion cross section;
- a cap portion welded to said metallic channel portion with a high energy, localized weldment of said cap portion to said channel portion;
- and
- a bar rolling apparatus for shaping said channel portion, cap portion and powder, while said powder is with said channel portion and said cap portion is welded to said channel portion.
A system for mechanically forming a ceramic superconductor product, comprising:
- a continuous metallic channel portion having a cross section for receiving a ceramic superconductor powder, said metallic channel portion holding a layer of silver metal adjacent a layer of said ceramic superconductor powder;
- means for mechanically compacting said ceramic superconductor powder, said means for compacting further having a complementary cross section matingly receivable by said channel portion cross section;
- and
- a cap portion having a high energy, localized weldment coupling said metallic channel portion to said cap portion.
