摘要： A process for gas diffusion coating of metallic components; in which a component surface which is to be coated is brought into contact with a metal halide as coating gas, to form a diffusion layer with a defined layer thickness and a defined coating metal content in % by weight in the component surface, working on the basis of a nominal concentration of the metal halide at the component surface which, at a defined coating temperature, leads to a defined coating time, wherein a first concentration, which is higher than the nominal concentration, for the metal halide is established for a first time, and at least one second concentration, which is at or below the nominal concentration, is established at the component surface for at least one second time, the first and the at least one second time being selected in such a way that their sum is shorter than the coating time with the nominal concentration.

摘要： A method for producing a high-temperature protective layer containing metal on a metallic high-temperature material is disclosed. The metal is deposited on the high-temperature material via the gaseous phase to form the high-temperature protective layer. The high-temperature material is held at a diffusion temperature for a specific length of time so that at least a portion of the deposited metal is diffused into the high temperature material to form a diffusion zone and where the high-temperature material is not in contact with solids or liquids in the region of the surface to be coated, but merely has a solid/gas interface. Also disclosed is a component made of a high-temperature material with a hot-gas anti-corrosive layer containing chromium. There is a coating layer containing chromium applied to the surface of the high-temperature material, a diffusion layer in the high-temperature material, and a build-up zone between the coating layer and the diffusion layer.
