A component has a solid structure that is manufactured using a laser or electron beam in an additive manufacturing process. The solid structure is formed from at least one material selected from the group consisting of molybdenum, a molybdenum-based alloy, tungsten, a tungsten-based alloy, and a molybdenum-tungsten-based alloy. The component includes one or more alloying element which at least in the temperature range ≥1500° C. has/have a reducing effect, as follows: in the case of molybdenum and the molybdenum-based alloy, for MoOand/or MoO; in the case of tungsten and the tungsten-based alloy, for WOand/or WO; and, in the case of the molybdenum-tungsten-based alloy, for at least one oxide from the group of MoO, MoO, WOand WO. The alloying element, or at least one of the alloying elements, is present both in at least partially unoxidized form and in oxidized form.

Metallization for a thin-film component, process for the production thereof and sputtering target

A process for producing a layer or a body built up of layers. A process gas which has a pressure of &#x3e;10 bar is accelerated in a convergent-divergent nozzle and a coating material which is formed by particles and is composed of Mo, W, an Mo-based alloy or a W-based alloy is injected into the process gas. The particles are at least partly present as aggregates and/or agglomerates. It is possible to produce dense layers and components in this way. We also describe layers and components having a microstructure with cold-deformed grains having a high aspect ratio.

A method for producing an electric lamp having a vitreous lamp bulb and a foil of molybdenum or a doped molybdenum alloy which is pinched in the lamp bulb includes post-treating the unfinished foil such that substantially non-contiguous, insular regions of material agglomerates are formed. The material agglomerates are formed of molybdenum, molybdenum alloys, titanium, silicon, an oxide, a mixed oxide and/or an oxidic compound, with a vapor pressure of in each case less than 10 mbar at 2000&deg; C. The substantially non-contiguous, insular regions are formed on at least 5 percent and at most 60 percent of the area of the foil surface. In this way, the adhesive strength between the foil and the glass and therefore also the service life of the lamp are significantly improved.
