Working Principle of ICCP Anode System
ICCP anode system is mainly composed of a DC power supply, anode, cathode (protected metal structure), reference electrode and connecting cable. The DC power supply provides external current, which flows from the anode, passes through the electrolyte (such as seawater, soil, etc.), and flows to the protected cathode metal. In this process, the anode undergoes an oxidation reaction, consuming its own material (soluble anode) or causing the ions in the electrolyte to undergo an oxidation reaction (insoluble anode), while the cathode metal surface undergoes a reduction reaction, mainly the reduction of oxygen (in a neutral or alkaline aerobic environment) or the reduction of hydrogen ions (in an acidic environment). The reference electrode is used to monitor the potential of the protected metal in real time, provide a basis for adjusting the DC power supply output, and ensure that the protected metal is always within the effective protection potential range.
Comparison of Different ICCP Anodes
Common ICCP anodes include steel anodes based on metal materials, high silicon cast iron anodes, mixed metal oxide (MMO) anodes with special coating technology, platinum-coated anodes, and graphite anodes made of non-metallic materials. Steel anodes are low in cost and can provide a large current output in the early stage, but they are consumed quickly. High silicon cast iron anodes rely on their good corrosion resistance and relatively low consumption rate. MMO anodes utilize mixed metal oxide coatings on titanium substrates to provide efficient current distribution and corrosion resistance. Although platinum-coated anodes are expensive, they have extremely high stability and extremely low consumption rates. Graphite anodes play a role in specific environments due to their good conductivity and acid resistance.

| Silicon – iron Anode | Resistant to high – resistivity soil, low cost | Heavy weight, requires regular maintenance | Deep well ground beds, long – distance pipelines |
| Graphite Anode | Good electrical conductivity, resistant to acidic environments | Prone to embrittlement, high consumption rate | Early cathodic protection systems |
Advantages of ICCP anode
ICCP anodes have an indispensable position in the field of modern industrial corrosion protection due to their advantages such as high efficiency protection, long life, high adaptability, flexible adjustment, environmental sustainability and significant economic benefits.
- Powerful Current Output Capability
ICCP anode is connected to an external DC power supply to output a stable and powerful current. For example, in large ships, the large metal shell has a large area and a high risk of corrosion. The ICCP anode can provide sufficient current to ensure that the entire hull surface can obtain enough electrons, effectively inhibiting the oxidation corrosion of the metal.
- Precise Protection Range Control
For the complex structure of the piers of the cross-sea bridge, which are immersed in seawater for a long time and partially exposed to the atmosphere, the current distribution can be accurately adjusted for different corrosion environment areas to enhance the protection of the underwater parts that are prone to corrosion.
- High-Quality Materials
ICCP anodes are mostly made of high-performance materials such as titanium-based platinum plating and mixed metal oxides. They have excellent corrosion resistance and can remain stable for a long time in harsh environments, such as marine\chemical high acid and alkali environments.
- Environmentally Friendly
ICCP anodes do not use or rarely use substances that are harmful to the environment. During its operation, it will not release toxic and harmful heavy metal ions into the surrounding environment, and will not pollute the soil, water and atmosphere, which is in line with modern environmental protection concepts.
- Improve Efficiency
For industrial production equipment, such as chemical reactors, oil storage tanks, etc., the effective protection of ICCP anodes ensures stable operation of the equipment, reduces equipment failures and downtime caused by corrosion, ensures production continuity, and thus improves efficiency.
- Compatible With Variety Of Metals
Applied to metal structures of different materials such as steel, aluminum, and copper for corrosion protection. In the aerospace field, ICCP anodes prevent key aluminum parts from being corroded under complex climatic conditions. Some key steel parts in cruise ships can also benefit from ICCP anodes.
Shaps of ICCP Anodes
Each ICCP anode shape has its own unique characteristics and application scenarios, including tubular, strip, can, mesh, rod, flexible and hull anodes. Each form provides targeted anti-corrosion protection, and users can choose the most suitable solution according to the specific needs of the project. In practical applications, it is necessary to comprehensively consider environmental factors, the characteristics of the protected metal structure, economic costs and system performance requirements, and reasonably select the ICCP anode type to achieve the best cathodic protection effect.

MMO Flexible Anode
MMO flexible anode is a new type of ICCP anode, which is based on a flexible conductive core, usually a copper core or copper-plated steel core, and is coated or wrapped with a layer of electrochemically active MMO material. This structure makes the anode both flexible and highly efficient in electrochemical performance.

Customized ICCP Anodes: For Optimal Cathodic Protection
Customizing ICCP anodes is a complex and systematic project, involving multiple links such as evaluation, type selection, design and manufacturing, installation and commissioning, maintenance and management. It is also necessary to fully consider the characteristics of the protected object, the service environment, budget and other factors, and comprehensively apply knowledge of materials science, electrochemistry, engineering design, etc. to ensure that the customized anode can meet the requirements of efficient and reliable cathodic protection. Through strict quality control and scientific maintenance management, the service life of the anode can be extended, the operating cost of the system can be reduced, and a strong guarantee can be provided for the long-term safe operation of metal structures.
Anode Size Design
The size of the anode mainly includes length, diameter (or thickness), etc., which needs to be determined according to factors such as the required protection current, the current output capacity of the anode, and the service life. Generally speaking, the larger the surface area of the anode, the greater the protection current it can provide. The surface area of the anode can be determined by calculating the total protection current required for the protected object and combining the current density parameter (current output capacity per unit area) of the selected anode material. For example, if the protection current required for an underground pipeline is 10A, and the recommended current density of the selected high-silicon cast iron anode is 0.1A/dm², the required surface area of the anode is 100dm².
Anode Shape Design
The shape of the anode should be designed according to the structural shape and installation space of the protected object. Common anode shapes include tubular, rod, strip, disc, flat plate, etc. Tubular anodes are suitable for long-distance pipeline protection. Strip anodes have good flexibility and can fit tightly to metal surfaces of complex shapes, such as the hull of a ship, the inner wall of a storage tank, etc. Disc anodes are often used for centralized protection of small equipment or specific areas. Flat anodes are suitable for large-area flat structures, such as the deck of an offshore platform, concrete foundation, etc. When designing the shape of the anode, the uniformity of the current distribution must also be considered to avoid the situation where the local current is too large or too small. For example, for flat anodes, special current distribution auxiliary structures, such as a grid-like conductive layer, can be set on the surface of the anode to improve the current distribution.
Anode Manufacturing
Steel anodes are usually manufactured by casting or forging processes. The steel raw materials are first melted and poured into a mold for molding, and then processed and surface treated. The manufacturing process of high-silicon cast iron anodes is relatively complicated. High-silicon ferroalloys need to be smelted and cast, and then mechanically processed and heat treated to improve their performance. Graphite anodes are generally made by pressing and sintering graphite powder or graphite blocks. The key to the manufacture of MMO anodes lies in the preparation of coatings. Commonly used methods include thermal decomposition and electrochemical deposition. First, one or more layers of mixed metal oxide precursor solution are coated on the surface of the metal substrate, and then heated or electrochemically treated to convert it into a catalytically active oxide coating. The manufacture of platinum-coated anodes mainly adopts electroplating or chemical plating methods to plate a uniform platinum coating on the surface of the metal substrate.
Quality Inspection
In the quality inspection of raw materials, chemical composition analysis, metallographic structure analysis, mechanical property testing, etc. of metal materials are carried out to test whether their composition, organizational structure and mechanical properties meet the requirements. For coating materials, such as mixed metal oxide precursor solutions, platinum salt solutions, etc., their purity, concentration and chemical composition can be tested by chemical analysis, spectral analysis and other methods. After the anode is manufactured, the inspection items include appearance inspection, size measurement, conductivity test, corrosion resistance test, current output performance test, etc.
Cost of ICCP Anode
The cost of ICCP anodes covers many aspects. The cost of raw materials is a key part. Materials such as titanium, which are corrosion-resistant and often used as MMO anode substrates, are relatively expensive. Niobium is even more expensive due to its scarce resources and difficulty in refining. Although steel is cheap, it has poor corrosion resistance. Among coating materials, MMO coatings composed of precious metal oxides such as ruthenium and iridium account for a large proportion of the cost due to metal price fluctuations.
Simple casting has low cost. Although extrusion, precision casting, 3D printing, etc. can achieve complex shapes and high precision, the equipment investment and processing costs are high. When preparing the coating, the thermal decomposition method has simple equipment and relatively low cost, but the coating performance is slightly inferior; the electrochemical deposition method can obtain high-quality coatings, but the cost increases due to equipment and reagent consumption.

The performance, selection, installation and maintenance of impressed current cathodic protection systems are crucial to the effectiveness and stability of the entire cathodic protection system. Different types of anodes, such as soluble anodes and insoluble anodes, each have their own characteristics and applicable scenarios. In practical applications, it is necessary to comprehensively consider the characteristics of the protected structure, environmental factors, economic factors, system compatibility and other factors, select the appropriate anode type, and carry out reasonable design, installation and maintenance.
