Abstract
In a cold gas spraying method, a gas jet (15) into which particles (19) are introduced is generated with the aid of a cold gas spray gun (20). The kinetic energy of the particles (19) results in a layer being formed on a substrate (13). The substrate is provided with a structured texture (24) which is transferred to the layer (20) that is formed. The method makes it advantageously possible to produce a high-temperature superconducting layer on the substrate (13) by selecting an appropriate particle (19) composition. The process can be additionally supported using a heating device (25) in a subsequent thermal treatment step.
