  • Descripción: An enhanced mixed metal oxide (MMO) coating is deposited by arc-plasma spray and chemical processing, the coating consists of Iridium, Tantalum, Titanium and Oxygen resulting in a dense abrasion resistance insert catalytic surface on commercial pure Titanium. The mixed metal oxide is crystalline, electrically conductive coating that activates Titanium and enables it to function as an anode. Such anodes are receiving great attention as an alternative to the conventional anodes in the cathodic protection industry. An experimental investigation was carried out to determine the physical and electrochemical characteristics of a typical MMO anode largely used in deep ground bed installations. The results have shown that such anodes are practically insoluble in acid, have an excellent adhesion to the Titanium tubular substrate, and above all, agreement with reported value of their breakdown potential has been established. The study has also shown that such anodes are not suitable for sulfate-rich environment. The low consumption rate makes these anodes commercially attractive for long term use.
