Abstract

In a method for depositing a non-metallic, in particular ceramic, coating on a substrate (2) by cold gas spraying, the method has the steps of: producing a reactive gas flow (5) having at least one reactive gas, injecting into the reactive gas flow (5) particles (4) consisting of at least one material required for producing a non-metallic, in particular ceramic, coating material by reaction with the reactive gas, so as to form a mixture flow of reactive gas and particles (4), producing reactive gas radicals in the mixture flow, and directing the mixture flow having reactive gas radicals and particles onto a surface of a substrate (2) to be coated, and so a non-metallic, in particular ceramic, coating is deposited on the surface of the substrate (2). In addition, a description is given of a device (1) for carrying out the method.
