Coated metal articles

A metallic uranium article having a protective coating consisting of aluminum separated from the uranium by an interlayer of an alloy containing copper and tin a weight ratio of from 20 to 75 of copper to form 80 to 25 of tin.

A metallic uranium article having a protective coating comprising a layer of substantially pure aluminum bonded to the uranium by a layer of lower melting aluminum-silicon alloy containing from 10 to 15% by weight of silicon and from 90 to 85% of aluminum, said latter alloy being separated from the uranium by a substantially thinner layer or copper alloy containing about 33% of tin.

A uranium article coated with an alloy consisting sub-stantially of 67% by weight of copper and 33% by weight of tin.

A uranium article coated with an alloy consisting sub-stantially of 47% by weight of copper and 53% by weight of tin.

A uranium article coated with an alloy consisting sub-stantially of 57% by weight of copper and 43% by weight of tin.

A uranium article coated with an aluminum-base metal and a layer of a copper-tin alloy containing copper and tin in a weight ratio of from 20 to 75 of copper to from 80 to 25 of tin therebetween.

A metallic uranium article having a protective coating of a ternary alloy containing approximately 1% of aluminum and copper and tin in a weight ratio of from 20 to 75 copper to from 80 to 25 tin.
