MMO Mesh Ribbon Anode

This MMO mesh ribbon anode is manufactured from an expanded titanium mesh substrate coated with mixed metal oxides. The mixed metal oxide coating, with industrially proven lifetime characteristics, ensures an even current distribution along the anodes length.

As a highly conductive anode with extremely low consumption rate, the titanium substrate is unchanged throughout the design life of the anode.

Our MMO mesh ribbon anode is manufactured using a bespoke automated production line which ensures meticulous titanium substrate preparation and a homogeneous coating application with superior adhesion properties. The current production capacity is up to one million meters per year.

Typically, MMO mesh ribbon anodes are a key component for impressed current cathodic protection of new build reinforcement concrete structures and existing concrete structures. For new build structures, the mesh ribbon anode is simply attached onto the rebar embedded in concrete/mortar before the concrete is poured. For retrofit applications, the mesh ribbon anode can be inserted into slots cut into the concrete surface.

In addition, the MMO mesh ribbon anode is field assembled with titanium conductor bars and a resistance welder. It has been proved to be a very effective way of controlling corrosion of rebar, particularly in hot and saline conditions.

Quality Substrate Material
The titanium substrate of the anode is selected according to ASTM B265 Grade 1 standard requirements. The high purity titanium has proven excellent chemical corrosion resistance, low electrical resistance, and high mechanical integrity against damage.

Noble Metal Oxide Coating
The Ir–Ta (IrO2/Ta2O5) mixed metal oxide catalyst, sintered to the surface of titanium substrate, demonstrates high chemical stability when exposed to high current density. We are able to produce anodes with differing coating thickness and noble metal oxide ratios. Strict quality procedures are followed throughout the coating process to ensure appropriate coating thickness and adhesion.

Long Working Life
The MMO coating film on the titanium mesh creates a protective stable layer ensuring a low consumption of the anode. These anodes can have a life expectancy of 100 years based on a 10 mA/ft² (110 mA/m²) current density.
