METHOD FOR PRODUCING A LAYER

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 proce...

description 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.
