MMO Ribbon Anode For Cathodic Protection Applications

Corrosion of embedded steel can become a long-term durability concern, particularly when moisture, chlorides, and other corrosive conditions are present. Corrosion protection starts with understanding the operating environment and the condition of the metal structure. Different metal structures require different approaches to corrosion control.

Cathodic protection is one approach used to help control corrosion by shifting the electrochemical conditions at the protected metal surface. For ICCP systems, MMO Ribbon Anode serves as an auxiliary anode that distributes protective current to the protected structure.

Cathodic protection systems generally use two main methods: sacrificial anode cathodic protection and impressed current cathodic protection (ICCP). But how does an ICCP system differ from a sacrificial-anode system?

Sacrificial-anode systems generate protective current through the electrochemical potential difference between the sacrificial anode and the protected metal, while ICCP systems use an external DC power supply and an auxiliary anode.

MMO Ribbon Anode is designed for applications where a flexible and distributed anode configuration is needed. Its ribbon-shaped structure allows the anode to be arranged along different structural surfaces and layouts, making it suitable for reinforced concrete, bridge structures, storage tank bottoms, and other cathodic protection applications. 

2.1 How It Works

In an ICCP system, a DC power supply drives current from the MMO ribbon anode through the surrounding electrolyte toward the protected metal structure. This shifts the protected metal in the cathodic direction and helps reduce its corrosion rate.

DC Power Supply → MMO Ribbon Anode → Electrolyte → Protected Steel Structure

2.2 MMO Ribbon Anode Parameters

The following values are the current standard product parameters prepared for this website page. Project-specific dimensions, coating, coil length and electrical connection can be customized.

    Material Properties

• Coefficient of Thermal Expansion: 8.7 × 10⁻⁶ /K at 20°C
• Thermal Conductivity: 15.6 W/(m·K) at 20°C
• Electrical Resistivity: 0.56 × 10⁻⁶ Ω·m
• Coating: Mixed Metal Oxide (MMO)
• Coating System: Iridium-Tantalum

If your project has a specified current output, design life, coating requirement or installation layout, please include those requirements in the inquiry so the configuration can be reviewed before quotation.

2.3 Where Is MMO Ribbon Anode Used?

(​1) Bridge and Reinforced Concrete Cathodic Protection

MMO ribbon anodes can be used for reinforced concrete structures, including bridge piers, reinforced concrete structures, jetty piles, concrete building surfaces and other reinforced concrete structures requiring cathodic protection. The ribbon can be installed using conductive adhesive, while its flexible form allows it to adapt to different structural surfaces and configurations.

(2) Storage Tank Bottoms Cathodic Protection

MMO ribbon anodes can also be used for storage tank bottom cathodic protection. For tank-bottom applications, MMO ribbon can be welded to titanium conductor bars and arranged as an anode grid before installation. The ribbon can be laid in the required configuration according to the CP system design.

Selection should not be based on product shape alone. A practical selection process is to first choose the anode configuration for the structure, then select the coating system for the operating environment, and finally confirm dimensions, connection method and electrical requirements.

3.1 Choose the MMO Anode Configuration

Different anode geometries are used because installation space, protected surface geometry and current-distribution requirements vary from project to project.

• MMO Ribbon Anode – commonly used for tank bottoms, bridge piers and concrete surfaces where a flat, distributed layout is required.
• MMO Tubular Anode – used for deep-well or other installations where a tubular geometry is preferred.
• MMO Flexible Anode – suited to complex or irregular structures that require a flexible distributed configuration.
• Probe Anode – used for specific localized protection requirements.
• Titanium Anode Wire – used for selected distributed linear anode arrangements.

3.2 Choose the Coating System

The MMO coating should be selected according to the electrolyte and the electrochemical duty of the project. For the current product range:

• Ir-Ta coating: typically used for soil, freshwater, concrete and oxygen-evolution service.
• Ru-Ir coating: typically used for seawater, high-salt and marine environments.

Coating selection should be confirmed against the actual project environment and cathodic protection design.

3.3 Select the Right MMO Anode

The table below is a practical starting point for matching common project conditions with a suitable anode geometry. 

For final selection, please provide the protected structure, operating environment, available installation space, required current or CP design data, expected service conditions and any applicable project standards.

At Ehisen, we take quality control seriously. Our inspection procedures cover the key stages of production, including titanium substrate verification, dimensional inspection, process inspection, coating appearance, coating adhesion, and applicable electrochemical performance testing.
