METHOD FOR PRODUCING A LAYER

WIPO Patent Application WO/2016/000004

A3

The invention relates to a method for producing a layer or a body that is composed of stacked layers, wherein a process gas having a pressure of > 10 bar is accelerated in a convergent-divergent nozzle and a coating material, which is formed from particles and made of Mo, W, a Mo base alloy or a W base alloy, is injected into the process gas. The particles are, at least partially, in the form of aggregates and/or agglomerates. It is thus possible to produce density layers and components. The invention further relates to layers and components having a microstructure, which comprises cold-formed grains having a high degree of expansion.
