Abstract

The corrosion-protected electrodes proposed comprise an inexpensive metal, which is not corrosion-resistant, as the substrate, and are provided with a coating of titanium nitride, giving the electrode good chemical resistance coupled with a high degree of surface resistance to mechanical wear.

Description

Die vorliegende Erfindung betrifft eine Korrosions­ schutzelektrode nach dem Oberbegriff des ersten Anspruchs. Derartige Elektroden dienen dem Schutz von metallischen Gegenständen gegen den elektrochemischen Angriff von ionenleitenden Medien, mit denen sie in Berührung kommen. Sie sind entweder als sogenannte Opferanoden aus billigen Stoffen, z. B. Zink hergestellt und schützen das Objekt, an dem sie befestigt sind, z. B. in See­ wasser eintauchende stählerne Schiffsrümpfe durch den zwischen ihnen und dem Elektolyten auftretenden katho­ dischen Strom; oder sie sind selbst aus einem korro­ sionsfesten Material, z. B. Niob-Platin hergestellt oder mit einem Überzug aus diesem Material versehen, wobei eine äußere elektrische Spannung an sie angelegt wird. Bei Verwendung von Opferanoden wird der Elektrolyt durch das in Lösung gehende Elektrodenmaterial verunreinigt, was bei bestimmten chemischen Prozessen unerwünschte Auswirkungen hat. Korrosionsfeste Materialien der genann­ ten Art sind teuer, wodurch erhebliche Kosten für die Elektroden aufzuwenden sind.The present invention relates to corrosion protective electrode according to the preamble of the first claim. Such electrodes serve to protect metallic Objects against the electrochemical attack of ion-conducting media with which they come into contact come. They are either called sacrificial anodes from cheap fabrics, e.g. B. Made and protect zinc the object to which they are attached, e.g. B. at sea steel hulls immersed in water through the between them and the katho occurring electricity; or you are from a corro yourself Sion resistant material, e.g. B. niobium platinum or coated with this material, with an external electrical voltage applied to them becomes. When using sacrificial anodes, the electrolyte contaminated by the electrode material going into solution, which is undesirable in certain chemical processes Has an impact. Corrosion-resistant materials called ten kind are expensive, which means considerable costs for the Electrodes are to be used.

Aufgabe der vorliegenden Erfindung ist eine Verbesserung der Korrosionsfestigkeit von Schutzelektroden durch deren Beschichtung mit einem billigeren Stoff, der eine hohe chemische Beständigkeit gegen die meisten in Frage kommen­ den Elektrolyten bei ausreichender elektrischer Leitfähig­ keit aufweist. The object of the present invention is an improvement the corrosion resistance of protective electrodes by their Coating with a cheaper fabric that is high chemical resistance to most of them the electrolyte with sufficient electrical conductivity ability.  

Die Lösung dieser Aufgabe erfolgt durch die im kenn­ zeichnenden Teil des Patentanspruchs angegebenen Mittel. Der genannte Stoff erfüllt die vorhergehend genannten Forderungen und liefert zugleich eine glatte und harte Oberfläche, die die Elektroden weitgehend vor mechanischen Beschädigungen im Mikrobereich (Abra­ sion) schützt. Der eigentliche Elektrodenkörper kann dann aus einem beliebigen billigen Metall hergestellt werden. Verfahren zum Abscheiden dünner Schichten der genannten Verbindungen auf Gegenständen jeder Form sind dem Fachmann bekannt, so z. B. Reaktionen aus der Gas­ phase. Als besonders geeignet erscheint jedoch ein Verfahren des Abscheidens aus einer in einer dünnen Gasatmosphäre unterhaltenen Lichtbogenentladung.This problem is solved by the in the kenn drawing part of the claim specified Medium. The mentioned substance fulfills the previous one mentioned demands and at the same time delivers a smooth and hard surface that the electrodes largely against mechanical damage in the micro range (Abra sion) protects. The actual electrode body can then made from any cheap metal will. Process for depositing thin layers of mentioned connections on objects of any shape known to the expert, such. B. Gas reactions phase. However, one appears to be particularly suitable Process of depositing from a thin Arc discharge maintained gas atmosphere.
