Titanium anodes, especially those coated with precious metal oxides like ruthenium-iridium, are widely used in brine electrolysis antifouling for their outstanding electrochemical performance. The core advantage lies in the synergy between the titanium substrate and the coating—titanium’s inherent resistance to chloride ions combines with the ruthenium-iridium oxide coating as an efficient catalyst, lowering the potential for chlorine evolution and converting brine into bactericidal hypochlorous acid to inhibit marine biofouling.
Brine electrolysis antifouling operates on a straightforward principle: an electric current drives electrochemical reactions at the titanium anode, converting chloride ions into oxidizing active chlorine. The key lies in coating technology advancements—early single ruthenium coatings prone to cracking have evolved into gradient-designed ruthenium-iridium-titanium composite coatings, which not only enhance catalytic efficiency (reducing chlorine evolution overpotential by ~0.3V) but also maintain stability in seawater. For example, a coastal power plant used a three-layer ruthenium-iridium-titanium anode that showed <5μm coating loss after 3 years of continuous operation in 35°C seawater.
Advantages
Exceptional Longevity: Compared to traditional lead-silver anodes, titanium anodes last 5–8 years in seawater with 3,000ppm chloride ions. A ship cooling system case showed that gentle rinsing with 5% dilute hydrochloric acid to remove calcium-magnesium deposits extended lifespan by 20%.
Energy Efficiency: After replacing anodes with ruthenium-iridium-titanium in a chemical park’s circulating water system, the cell voltage dropped from 6.8V to 5.2V, saving ~150,000 kWh annually—attributed to improved current efficiency (from 82% to 95%).
Environmental Friendliness: Unlike lead anodes releasing heavy metals, precious metal coatings on titanium anodes can be recycled professionally. One environmental firm’s technology recovers 99% of iridium, drastically reducing hazardous waste treatment costs.
Application
Marine equipment: It is widely used in the anti – fouling systems of coastal power plants, nuclear power plants, and ships.For example, in the cooling water systems of these facilities, titanium anodes are used to electrolyze seawater to produce active chlorine, which prevents the attachment and growth of marine organisms on the inner walls of pipelines and equipment, ensuring the normal operation of the cooling water systems.
Industrial circulating water systems: In some industrial production processes, such as in chemical plants and steel plants, circulating water systems are prone to fouling problems. Brine electrolysis anti – fouling technology using titanium anodes can be used to treat circulating water, kill bacteria and algae in the water, and prevent the formation of scale and bio – fouling, thereby improving the efficiency and service life of the circulating water systems.

production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
