Abstract
The inside of a sheath of titanium, zirconium or tantalum (or an alloy of one of said metals) is coated with a tinning metal or alloy by heating the sheath while the inside of the sheath is covered with the molten tinning metal, and moving an ultrasonically excited probe over substantially the whole of the outer surface of the sheath, said probe being in contact with the outer surface of the sheath. The coated sheath is then bonded as by soldering to a metal article such as copper or aluminum.
