We reverse.
BACKGROUND
The disclosed invention is directed to a method of
making a superconductor cable having a nickel coating on the
superconducting wire strands in the cable.
Claim 1 is reproduced below.
1. In a method for making superconductor cable, the
steps comprising:
(a) encasing a multiplicity of filaments of a
superconductor alloy in a normally conducting metal
matrix to form superconductor wire;
(b) electroplating with nickel said superconductor
wire to provide a nickel coating about the periphery
thereof;
(c) forming an elongated bundle of generally
circular cross section from a multiplicity of strands
of said electroplated superconductor wire; and
(d) deforming and compacting said bundle of
strands into a superconductor cable of generally
polygonal cross section, said nickel coating on said
strands substantially maintaining its integrity in said
cable, and said strands exhibiting only negligible
diffusion of nickel into the matrix metal of said
