Abstract

Uranium rods or other articles are protected by coating with iron, preferably by electro-deposition. Over-coatings of Al, Cu, Zn, brass, Cd, Pb or Sn may be applied either by plating or hot-dipping. Under-coats of Ni or Zn may also be applied. The iron coated and plated rod may then be heated at 450 DEG to 500 DEG C. to form alloys between successive coatings. The rod may be pre-heated by light sand blasting, or etching with HCl, HNO3, tri-chloracetic acid or molten hydrate of ferric chloride. In examples (A) a cleaned uranium rod is (1) electroplated with Fe, and then Cu, (2) dipped in molten tin (3) dipped in molten Al/Si alloy. The rod is heated to alloy the Cu/Sn inner coating; (B) a uranium rod plated with iron is heated to 475 DEG C., dipped in molten aluminium solder (90% Sn, 10% Zn) and sheathed in an aluminium jacket, while the solder is molten.
