Abstract

A uranium rod is coated with Cu, Cr, Si or Zr, whilst rotating, by vapour deposition using a molybdenum crucible or a helical tungsten resistance heater. A second coating of another metal of the said group may be applied by vapour deposition or diffusion from powder or thin foil wound round the rod and heated. Before coating the rod is machined, degreased in acetone, anodically pickled in 10% HNO 3 and rinsed in dilute acid and then in pure alcohol.A uranium rod is coated with Cu, Cr, Si or Zr, whilst rotating, by vapour deposition using a molybdenum crucible or a helical tungsten resistance heater.
