The mechanism of hydrogen permeation through high-temperature alloys and through oxidized high-temperature alloys which probablywill be used in the project "Nukleare ProzeBwArme", is escamined. The escamined steels are "Hastelloy X" and "Inconel 617" which are, in a special oxidizing procedure, protected by an oxid layer (2-10$\mu$m thick). The hydrogen permeation through oxidized metall alloys is described, a model of this work, by the volume parameters solubility and diffusion coefficient of the oxide and the alloy. Surface treatment of the oxide scale is of no in fluence on the permeation rate. The diffusion process through the oxidscale is described in the model by two parallel, independent pathes. The first path is the diffusion through the undisturbed oxid, and the second path is understood as cracks, micropores or something else. |
