1152483 Coating by spraying UNION CARBIDE CORP 13 May 1966 [17 May 1965] 21273/66 Headings H1A A5 and A4D Super-conducting materials, e.g. Nb, Sn, Zr, Al, V, Si, Nb-Zr-Sn or Nb-Zr or compounds e.g. Nb 3 Sn Nb 3 A1 and V 3 Si are deposited on a substrate by plasma spraying, using the substrate as an electrode, and then heated after deposition. The gas may be argon, helium, nitrogen, and hydrogen. The starting materials may be in elemental or alloyed form. The substrate may be aluminium or brass which may be subsequently dissolved away. If a low-melting substrate is used it may be cooled during spraying. |
