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 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.
