Methods for forming diamond-coated superconductor wire

A method for forming electrical wire or cable that is superconducting of electricity, said method comprising:

• (a) forming an elongated wire-like substrate of metal,
• (b) providing a first layer of nonconducting material along the entire outer surface of said elongated wirelike substrate to form an insulated wire-like substrate having an outer insulated surface,
• (c) continuously feeding said insulated wire-like substrate to the die of an extruder,
• (d) operating said extruder to extrusion cover the entire outer insulated surface of said insulated wire-like substrate with a metallic superconducting material as it passes through said die, and
• (e) continuously forming a second layer comprising synthetic diamond material on the outer surface of said superconducting material.

A method of fabricating an elongated superconductor wire or cable, said method comprising:

• (a) forming an elongated substrate,
• (b) moving and guiding said substrate in a select path coincident with the axis of elongation of said substrate,
• (c) forming a metallic superconducting compound in situ on the entire exterior surface of said substrate as it is driven along said select path, and
• (d) forming an insulating synthetic diamond coating on the entire exterior surface of said metallic superconducting compound.

A method for producing an elongated conducting member for transmitting electricity comprising:

• (a) continuously forming and feeding an elongated metallic superconductive member of substantially constant cross-section along its length,
• (b) passing said elongated member through a reaction zone of a reaction chamber, and
• (c) contiguously depositing a thin layer of synthetic diamond on the entire outer surface of said elongated member by flowing molecules of a fluent material containing carbon atoms through said reaction zone into contact with the outer surface of said elongated member,
• (d) said step (c) including generating and passing radiant energy through said fluent material in said reaction zone and said elongated member wherein said radiant energy is operable to cause carbon atoms of said fluent material to become deposited as a thin layer on the outer surface of said elongated member.
