Abstract (en)

[origin: WO02055754A2] The invention relates to a method and a device for gas phase diffusion coating of components (3), wherein a component surface (4) which is to be coated is brought into contact with a metal halogenide as a coating gas, forming a diffusion layer having a determined thickness and a determined metal content in wt % in the component surface, starting from a nominal concentration of metal halogenide on the component surface leading to a defined coating duration at a defined coating temperature. For the metal halogenide, a first concentration which is higher than the nominal concentration and at least one second concentration which is lower than the nominal concentration are adjusted on the surface (4) over a first period of time and at least a second period of time. The first and the at least one second period of time are chosen in such a way that the sum thereof is shorter than the coating duration with the nominal concentration.
