Processes for coating a temperature-stable component with a thermal protection layer

The invention relates to a process and a device for coating a temperature-stable component with a thermal protection layer, in which the temperature-stable component has a surface which is to be coated with the thermal protection layer and at which there is at least one cooling-passage opening which is connected to a cooling passage running inside the component. The invention also describes a temperature-stable component which can be produced using the above process. A process and a device for coating a temperature-stable component with a thermal protection layer (), in which the temperature-stable component has a surface () which is to be coated with the thermal protection layer () and at which there is at least one cooling-passage opening () which is connected to a cooling passage running inside the component. During the coating a mass flow () emerges through the cooling-passage opening (), the coating takes place by a coating mass flow () directed onto the surface () which is to be coated, and the mass flow () emerges through the cooling-passage opening () and the coating mass flow () include an angle ≠0°.
