Diamantelektroden

Die Lebensdauer von Diamant-Titanelektroden wird bei anodischer Belastung durch die elektrochemische Auflösung des Titankarbid Interfaces zwischen Diamant und dem Titansubstrat begrenzt. Mit Tantal oder Niob als wesentlich stabilere Elektrodenmaterialen lassen sich um Größenordnungen längere Lebensdauern der Diamantelektroden erreichen.

Ein neues Forschungsziel ist die Entwicklung von kostengünstigeren Diamantelektroden, für die zuerst Tantal oder Niob Zwischenschichten auf Titan- oder Stahlblechen aufgebracht werden. Danach erfolgt die Diamantbeschichtung mit Bor-Dotierung.
