    Abstract: The invention relates to a current inlet conductor assembly particularly for vacuum devices, especially for light sources such as incandescent lamps or discharge tubes, comprising an inlet conductor made of molybdenum for passing electric current and being surrounded by a vitreous material forming a hermetic seal therewith and an intermediate metal coating covering the surface of the inlet conductor at least on the places to be welded. The essence of the invention is that the intermediate metal coating is made of rhenium, advantageously with a thickness from 3 to 1200 nm. As proposed, the intermediate rhenium layer should be produced by electrolytic deposition, especially from an aqueous solution.
