The surface of a copper coil was coated by thermal spraying using a plasma spraying device under a reduced pressure atmosphere of argon. The coating method was carried out by scanning the thermal spray gun while rotating the coil. Nb strongly adheres to almost the entire surface of the coil, and the coating thickness is approximately 36 mm.
It was 0 μm. The coil used had a diameter of 1111 ffl. The Nb-coated copper coil thus obtained exhibited superconducting properties at liquid helium temperatures.

The alloy thus obtained also exhibited superconducting properties at helium temperatures. Furthermore, when a mixture of Nb and Ti was plasma sprayed in the atmosphere, Ti was severely oxidized and a good NbTi film could not be obtained.
