ABSTRACT:
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. Also disclosed is a device for the process.
