Abstract: A process for producing a layer or a body built up of layers. A process gas which has a pressure of >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.

Abstract: A powder metallurgical component has a chromium content of at least 80% by weight and pores and/or oxide inclusions which are present in the component. The number per unit area of a sum of pores and oxide inclusions at a cut surface through the component in at least one region is at least 10,000 per mm2.

Abstract: A powder-metallurgical sintered molybdenum part which is present as a solid body has the following composition: a molybdenum content of ≥99.93% by weight, a boron content “B” of ≥3 ppmw and a carbon content “C” of ≥3 ppmw, with a total content “BaC” of carbon and boron being in a range of 15 ppmw≤“BaC”≤50 ppmw, an oxygen content “O” in a range of 3 ppmw≤“O”≤20 ppmw, a maximum tungsten content of ≤330 ppmw and a maximum proportion of other impurities of ≤300 ppmw. A powder-metallurgical process for producing such a sintered molybdenum part is also provided.

Abstract: A powder or powder granulate includes a chromium content >80 Ma %, which contains 2 to 20 Ma % iron, optionally up to 5 Ma % dopant, and optionally up to 2 Ma % oxygen, wherein the chromium-containing particles at least partially have pores. The powder displays significantly improved compression behavior and allows the production of sintered components having a very homogeneous distribution of the alloy elements.

Abstract: A sputtering target containing molybdenum and at least one metal from the group tantalum and niobium. The average content of tantalum and/or niobium is from 5 to 15 at % and the molybdenum content is greater than or equal to 80 at %. The sputtering target has at least a matrix with an average molybdenum content of greater than or equal to 92 at % and particles which are composed of a solid solution containing at least one metal from the group of tantalum and niobium, and molybdenum, with an average molybdenum content of greater than or equal to 15 at % and are embedded in the matrix. There is also described a method of producing a sputtering target.

Abstract: A powder metallurgical molding forms an interconnector or an end plate for an electrochemical cell. The molding has a chromium content of at least 80% by weight, a basic shape of a plate and one or more flow fields with structuring formed on one or both of the main faces of the molding. A ratio of a maximum diameter Dmax of the molding, measured along the main face, to a minimum thickness dmin of a core region of the molding which extends along the flow field or fields and is not affected by the structuring lies in a range of 140≤Dmax/dmin≤350.
