Method for producing a metal-containing high-temperature protection layer on a metal high-temperature material, wherein the metal to be deposited is chromium or a chromiumcontaining alloy and the high-temperature material is an Ni-based alloy and/or a turbine-blade material, said method comprising the steps of: - depositing chromium on the high-temperature material via the gaseous phase in order to form the high-temperature protection layer, wherein the high-temperature material is kept at a diffusion temperature for a specific amount of time such that at least some of the deposited metal diffuses into the high-temperature material in order to form a diffusion zone, - there being no contact between the high-temperature material in the region of the surface to be coated and solids or fluids, there merely being a solid/gas interface, - heating donor metal particles and an activator to a given temperature such that the donor metal is deposited on the high-temperature material via volatile compounds of the donor metal with the activator, wherein the donor metal is arranged at a distance of from 0.1 to 200 mm from the high-temperature material to be coated, - carrying out the method in a reaction chamber, which method allows the reaction chamber to be flushed before and/or after coating and/or during a pure diffusion phase, wherein the reaction chamber is flushed with an inert or noble gas, in particular argon, - forming a ductile gradient protection layer based on chromium, comprising: - an overlay layer, - an inwardly directed diffusion layer and - a structural zone between the diffusion layer and the overlay layer, wherein the chromium content of the structural zone is between that of the diffusion layer and that of the overlay layer and the overlay layer has the modification of α-chromium and a chromium content of from 25 to 90 wt.%. - depositing chromium on the high-temperature material via the gaseous phase in order to form the high-temperature protection layer, wherein the high-temperature material is kept at a diffusion temperature for a specific amount of time such that at least some of the deposited metal diffuses into the high-temperature material in order to form a diffusion zone, - there being no contact between the high-temperature material in the region of the surface to be coated and solids or fluids, there merely being a solid/gas interface, - heating donor metal particles and an activator to a given temperature such that the donor metal is deposited on the high-temperature material via volatile compounds of the donor metal with the activator, wherein the donor metal is arranged at a distance of from 0.1 to 200 mm from the high-temperature material to be coated, - carrying out the method in a reaction chamber, which method allows the reaction chamber to be flushed before and/or after coating and/or during a pure diffusion phase, wherein the reaction chamber is flushed with an inert or noble gas, in particular argon, - forming a ductile gradient protection layer based on chromium, comprising: - an overlay layer, - an inwardly directed diffusion layer and - a structural zone between the diffusion layer and the overlay layer, wherein the chromium content of the structural zone is between that of the diffusion layer and that of the overlay layer and the overlay layer has the modification of α-chromium and a chromium content of from 25 to 90 wt.%. - an overlay layer, - an inwardly directed diffusion layer and - a structural zone between the diffusion layer and the overlay layer, wherein the chromium content of the structural zone is between that of the diffusion layer and that of the overlay layer and the overlay layer has the modification of α-chromium and a chromium content of from 25 to 90 wt.%.
