Abstract

Pressure vessel or bottle made of steel and used for storing gaseous hydrogen, has inner surface with protective layer made of a metal (a) without any d-band gaps. The pref. metals (a) are in the first or second sub-gp., or the third main gp. of the periodic system. The esp. pref. metals (a) are Zn, Cd, Ag, Au or Pb. Steel bottles etc. contg. H2 gas are damaged by hydrogen embrittlement and/or other defects due to the H2 entering the steel. Layer (a) prevents the H2 from reaching the steel.

Druckbehälter aus Stahl zur Aufbewahrung von gasförmigem Wasserstoff Steel pressure vessel for storing gaseous hydrogen

Die Erfindung betrifft einen Druckbehälter aus Stahl zur Aufbewahrung von gasförmigem Viasserstoff.The invention relates to a pressure vessel made of steel for storing gaseous hydrogen.

Es ist eine bekannte Erscheinung, daß Wasserstoff in atomarer oder ionisierter Form leicht in viele Metalle diffundiert. Insbesondere bei Stahl macht er sich hierdurchals "Metallschädling" bemerkbar. Die Schädigungen erfolgen bei Raumtemperatur oder nur wenig über der Raumtemperatur liegenden Temperaturen. Stahlschädigungen sind unter den Begriffen Flocken, Fischaugen, wasserstoffinduzierte Spannungsrisskorrosion, verzögerte Brücke, Wasserstoffversprödung u. ä. bekannt.Derartige Schädigungen können bei mit Wasserstoff gefüllten Druckgasbehältern zum Bersten der Behälter mit erheblichen Folgeschäden führen.It is a well known phenomenon that hydrogen in atomic or ionized form is easily converted into many Metals diffused. In the case of steel in particular, this makes it noticeable as a "metal pest". The damage occurs at room temperature or at temperatures only slightly above room temperature. Steel damage is classified under the terms flakes, fish eyes, hydrogen-induced stress corrosion cracking, Delayed bridging, hydrogen embrittlement, etc. are known. Such damage can in the case of pressurized gas containers filled with hydrogen, the containers burst with considerable consequential damage to lead.

Der Erfindung liegt die Aufgabe zugrunde, einen Druckbehälter aus Stahl zur Aufbewahrung von gasförmigem Wasserstoff zu schaffen, bei dem die Gefahr einer Schädigung durch den aufbewahrten Wasserstoff nicht gegeben ist.The invention is based on the object of a pressure vessel made of steel for storing gaseous To create hydrogen with the risk of damage from the stored hydrogen is not given.

Es wurde nun ein Druckbehälter aus Stahl zur Aufbewahrung von gasförmigem Wasserstoff gefunden, bei dem gemäß der Erfindung die Innenoberfläche mit einer Schutzschicht aus einem Metall ohne d-Bandlücken versehen ist.A pressure vessel made of steel for storing gaseous hydrogen has now been found in which according to the invention, the inner surface is provided with a protective layer made of a metal without d-band gaps is.

Die Formulierung "Metalle ohne d-Bandlücken" besagt, daß es sich um Metalle ohne Lücken in den d-Schalen der Elektronenhülle handelt. Besonders geeignet sind Metalle aus der ersten und zweiten Nebengruppe, sowie der dritten Hauptgruppe des periodischen Systems der Elemente. Gut geeignete Metalle sind beispielsweise Zink, Cadmium, Silber, Gold und Blei.The phrase "metals with no d-band gaps" indicates that they are metals with no gaps in the d-shells the electron shell acts. Metals from the first and second subgroups as well as are particularly suitable the third main group of the periodic table of elements. Suitable metals are, for example Zinc, cadmium, silver, gold and lead.

Durch die erfindungsgemäße Schutzschicht wird jegliche Wasserstoffversprödung des Stahls völlig vermieden.An einer ungeschützten Stahloberfläche wird der Wasserstoff chemi-sorbiert und geht anschließend in den okkludierten Zustand über. Der Anteil an interstitiell eingebautem Wasserstoff erhöht sich dadurch derartig, daß er durch Desorption in den Korngrenzen und inneren Poren die bekannten Effekte der Wasserstoffverprödung erzeugt.The protective layer according to the invention is any Hydrogen embrittlement of the steel completely avoided The hydrogen is chemisorbed on an unprotected steel surface and then goes into the occluded state. This increases the proportion of interstitially incorporated hydrogen to such an extent that that it has the well-known effects of hydrogen embrittlement through desorption in the grain boundaries and inner pores generated.

Die gemäß der Erfindung für die Schutzschicht verwendeten Metalle zeigen eine außerordentlich geringe Tendenz,Gase, insbesondere Wasserstoff, zu chemisorbieren und zu lösen. Insbesondere ihre Eigenschaft, den Wasserstoff nicht zu lösen, verhindert, daß der Wasserstoff durch die metallische Schutzschicht dringt und schließlich den Stahl angreift. Die metallische Schutzschicht kann galvanisch oder mechanisch auf die innere Oberfläche der Druckbehälter aufgebracht werden.The metals used according to the invention for the protective layer are extremely low Tendency to chemisorb and dissolve gases, especially hydrogen. In particular, their property Failure to dissolve the hydrogen prevents the hydrogen from penetrating through the metallic protective layer and finally attacks the steel. The metallic protective layer can be galvanically or mechanically applied to the inner surface of the pressure vessel are applied.

Die Zeichnung veranschaulicht als Ausführungsbeispiel der Erfindung eine Stahlflasche zur Aufbewahrung von gasförmigem Sauerstoff.The drawing illustrates, as an embodiment of the invention, a steel bottle for storing gaseous oxygen.

Die Stahlflasche 1 ist teilweise aufgebrochen dargestellt, so daß die Flaschenwand 2 aus Stahl mit der erfindungsgemäß aufgebrachten Schutzschicht 3 ,beispielsweise aus Blei, zu sehen ist.The steel bottle 1 is shown partially broken, so that the bottle wall 2 made of steel with the protective layer 3 applied according to the invention, for example made of lead, can be seen.
