The selection of materials is critical to ensure exceptional durability, corrosion resistance, and electrical efficiency. These anodes are widely used in cathodic protection systems, water treatment, electroplating, and chlor-alkali processes due to their reliable performance and extended service life.
Core Materials and Their Functional Roles
The performance of MMO Ti mesh anodes stems from a strategic combination of a titanium substrate and noble metal oxide coatings. Each material contributes uniquely to the anode’s structural integrity, conductivity, and resistance to degradation under aggressive operating conditions.
Corrosion-Resistant Titanium Substrate
Titanium serves as the foundational backbone of MMO anodes, providing mechanical strength and exceptional corrosion resistance. In marine, chemical, and industrial environments where chloride levels and pH extremes are common, titanium remains inert and stable, preventing substrate degradation.
The use of titanium mesh not only offers structural support but also ensures high surface area for efficient current distribution. Its excellent strength-to-weight ratio and resistance to abrasion allow the anode to maintain integrity over decades of continuous operation. Even under high current densities, the titanium base resists passivation, ensuring consistent electrical contact with the active coating layer.
Iridium Oxide Coating
Iridium, typically applied in the form of iridium oxide (IrO₂), is one of the most electrochemically stable materials used in MMO coatings. It provides outstanding catalytic activity for oxygen evolution reactions, making it ideal for anodes operating in acidic or neutral environments such as water disinfection and cathodic protection systems.
The dense, crystalline structure of iridium oxide enhances wear resistance and reduces coating consumption over time. Customizable coating thicknesses allow engineers to balance initial cost with expected service life—thicker coatings extend longevity in high-demand applications like seawater electrolysis or offshore platforms.
Platinum Group Alloys
Platinum is often alloyed with other noble metals (such as iridium or ruthenium) to improve catalytic efficiency while managing material costs. Pure platinum offers unparalleled corrosion resistance, especially in highly oxidizing chemical environments such as industrial electrolysis and hydrogen generation.
However, due to its high cost, platinum is typically used in thin, optimized layers or as part of a composite oxide matrix. These platinum-enhanced coatings deliver superior conductivity and stability, particularly in low-conductivity waters or intermittent current applications. The ability to tailor coating composition enables performance optimization for specific operational parameters like voltage, temperature, and electrolyte composition.
Ruthenium Oxide Coating

Key Factors in Selecting a Customized MMO Ti Mesh Anode
- Corrosive Environment
The operating environment plays a decisive role in determining the required anode durability and coating composition. In marine or seawater applications, where chloride levels are high, MMO anodes should be coated with a blend of ruthenium oxide and iridium oxide to maximize resistance to chlorine evolution and pitting corrosion. For underground or soil-based installations, such as pipeline cathodic protection, the soil's pH, resistivity, and chemical composition (e.g., sulfates, chlorides) must be analyzed. Anodes in acidic or high-resistivity soils may require thicker or specially formulated coatings to prevent passivation and ensure consistent current output.
- Application Requirements
Different industrial applications demand distinct anode characteristics:
- Marine Cathodic Protection: Requires robust, long-lasting anodes with uniform current distribution. Typically uses RuO₂-IrO₂ coatings on expanded titanium mesh for offshore platforms, ship hulls, and harbor structures.
- Electrolysis (e.g., chlor-alkali, water treatment): Needs high catalytic activity and dimensional stability. Iridium-based coatings are preferred for oxygen evolution reactions due to their stability in acidic environments.
- Industrial Electroplating: Requires a smooth, uniform surface to ensure even metal deposition. Precision-machined or woven Ti mesh with fine coatings ensures consistent current density and minimizes defects.
- Chemical Processing: Involves exposure to aggressive acids, alkalis, or solvents. Coatings must be chemically inert—often using tantalum or platinum group metals—to withstand prolonged exposure without degradation.
- Current Output and Distribution Needs
The electrical performance of the anode is directly influenced by its physical design. Customizing the mesh size, geometry, and surface area allows optimization of current density and distribution:
- Larger surface areas increase total current capacity, making them ideal for high-demand applications like large-scale cathodic protection systems.
- Finer mesh patterns (e.g., 1mm x 1mm) promote more uniform current distribution, which is critical in precision electroplating or sensitive electrolytic cells.
- Custom shapes (rectangular, cylindrical, or ribbon configurations) can be designed to match the cathode geometry, improving efficiency and reducing energy consumption.
Proper current distribution minimizes hot spots and ensures even wear, extending the anode’s service life.
- Substrate and Coating Material Selection
The choice of substrate and coating materials balances performance, longevity, and cost:
- Titanium (Grade 1 or 2): The most widely used substrate due to its excellent strength-to-weight ratio, natural oxide layer, and compatibility with MMO coatings.
- Ruthenium Oxide (RuO₂): Offers high conductivity and good performance in chloride-rich environments; cost-effective but less durable in highly acidic conditions.
- Iridium Oxide (IrO₂): Superior in acidic and oxygen-evolving environments; excellent stability but higher in cost.
- Platinum or Platinum-Tantalum: Used for extreme durability in highly corrosive or high-temperature applications, though at a premium price.
Hybrid coatings (e.g., RuO₂-IrO₂-Ta₂O₅) are often tailored to specific operational conditions to optimize performance and cost-efficiency.
- Coating Thickness and Lifespan
Coating thickness is a critical factor in determining the anode’s operational lifespan and performance:
- Thicker Coatings (10–20 µm): Provide extended service life in harsh environments by offering greater material reserves before depletion. Ideal for permanent installations where maintenance access is limited.
- Thinner Coatings (3–8 µm): Reduce material costs and can offer faster electrochemical response times, beneficial in high-current-density applications like pulse plating or rapid electrolysis.
However, excessively thin coatings may wear out quickly under continuous operation, while overly thick coatings can crack due to stress buildup during thermal cycling. Optimal thickness should be determined based on expected current density and operational hours.
| Selection Factor | Recommended Options | Performance Impact | Cost Consideration |
|---|---|---|---|
| Marine Environment | RuO₂-IrO₂ coating, expanded Ti mesh | High corrosion resistance, stable output | Moderate to high |
| Underground/Soil | RuO₂-based, variable thickness | Adaptable to soil resistivity | Low to moderate |
| Electroplating | Smooth Ti mesh, thin IrO₂ coating | Uniform deposition, low defects | Moderate |
| Acidic Electrolysis | IrO₂-Ta₂O₅ coating, fine mesh | Stable O₂ evolution, long life | High |
| Budget-Conscious Projects | RuO₂ coating, standard mesh | Good performance in mild conditions | Low |
Expert Tip: Always request a custom coating formulation and accelerated life testing data from your supplier when designing anodes for critical or non-standard applications. This ensures the anode will perform reliably under your specific operating conditions.
