Titanium anode for cathodic protection is widely used in impressed current cathodic protection (ICCP) systems for pipelines, storage tanks, marine structures, offshore platforms, and reinforced concrete structures. With excellent corrosion resistance, dimensional stability, and long service life, MMO coated titanium anodes provide reliable long-term corrosion protection in harsh environments.

🟩 What is Titanium Anode for Cathodic Protection?
A titanium anode for cathodic protection is an insoluble electrode manufactured from titanium substrate coated with mixed metal oxides (MMO), typically ruthenium-iridium or iridium-tantalum coatings.
It is designed for impressed current cathodic protection systems, where external DC current is applied to protect metal structures from electrochemical corrosion.
Titanium anodes are commonly used in:
- Oil and gas pipelines
- Underground pipelines
- Storage tanks
- Marine structures
- Offshore platforms
- Ship hulls
- Reinforced concrete structures
- Desalination plants
🟩 How Does Titanium Anode Work in ICCP Systems?
In an ICCP system:
- DC current is supplied from a rectifier
- Current flows from the titanium anode into the electrolyte
- The protected structure becomes the cathode
- Corrosion reactions are suppressed
This process shifts the electrochemical potential of the metal structure, preventing oxidation and material loss.
