Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Herstellen eines Wasserstoff-Druckbehälters (1), mit den folgenden Schritten: a) Bereitstellen eines metallischen Behälters (2) mit einer Innenseite (3) und einer Außenseite (4), b) Ausbildung einer sauerstoffhaltigen Oxidschicht (5) auf der Innenseite (3) des Behälters (2) mittels Oberflächen-Behandlung mit einem Sauerstoffplasma und/oder mittels Oberflächen-Wärme-Behandlung unter sauerstoffhaltiger Atmosphäre, c) Beschichten der in Verfahrensschritt b) ausgebildeten Oxidschicht (5) der Innenseite (3) des metallischen Behälters (2) mit einer Diffusions- Sperrschicht (20) in einem Niederdruckverfahren, insbesondere bei einem Druck von 0,1 bis 100 Pa, bevorzugt von 0,1 bis 10 Pa, wobei die in Verfahrensschritt c) durch Beschichtung erhaltene Diffusions-Sperrschicht (20) entweder - als ein alternierender Schichtaufbau (21) aus mindestens einer dehnbaren Zwischenschicht (6) und mindestens einer hochdichten Sperrschicht (7) oder - als eine Gradientenschicht (8), wobei die Gradientenschicht (8) einen, vorzugsweise kontinuierlichen, Gradienten von einem dehnbaren Material zu einem hochdichten Material aufweist, ausgebildet wird, d) Erhalt des Wasserstoff-Druckbehälters (1).
(EN)
The invention relates to a method for producing a hydrogen pressure vessel (1), having the following steps: a) providing a metal vessel (2) having an inner face (3) and an outer face (4); b) forming an oxygen-containing oxide layer (5) on the inner face (3) of the vessel (2) by treating the surface with an oxygen plasma and/or by thermally treating the surface in an oxygen-containing atmosphere; c) coating the oxide layer (5) formed on the inner face (3) of the metal vessel (2) in method step b) with a diffusion barrier (20) in a low-pressure process, in particular at a pressure of 0.1 to 100 Pa, preferably 0.1 to 10 Pa, the diffusion barrier (20) obtained by coating in method step c) being formed either - as an alternating layer structure (21) of at least one stretchable intermediate layer (6) and at least one high density barrier layer (7) or - as a gradient layer (8), the gradient layer (8) having a preferably continuous gradient from a stretchable material to a high density material; d) obtaining the hydrogen pressure vessel (1).
