Mesh anode titanium is an auxiliary anode material composed of a titanium substrate coated with a precious metal oxide layer. It is formed by cross-welding mixed metal oxide strip anodes with titanium metal connectors. Currently, two primary types of mesh anode titanium products exist on the market: woven wire mesh anodes and expanded sheet anodes. Titanium wire mesh anodes utilize pure titanium wire weaving technology, with thicknesses ranging from 0.12 to 4 mm and aperture sizes from 0.154 to 5 mm. Titanium plate expanded mesh anodes, conversely, are formed by directly stretching pure titanium plates. Finished thicknesses range from 0.5 to 3 mm, with common aperture configurations including diamond-shaped apertures such as 1×2 mm, 2×3 mm, and 3×6 mm. Both mesh anodes exhibit excellent electrical conductivity and surface area advantages. Stretched titanium plate mesh offers higher strength, superior flatness after heat treatment leveling, and faster gas release from the anode. Woven titanium wire mesh provides greater flexibility, making it suitable for installation on irregular surfaces.
Regarding performance parameters, high-quality mesh anode titanium typically operates within a temperature range of 17–80°C and can achieve a service life exceeding 20 years under standard current densities. The formulation of precious metal oxide coatings directly impacts the performance of mesh anodes. Common coatings consist of mixtures of precious metal oxides like iridium and tantalum, which provide exceptionally high electrocatalytic activity and reduce anode polarization. This ensures stable and highly efficient current output.
Mesh titanium anodes are primarily employed in cathodic protection systems, demonstrating exceptional performance in metal corrosion prevention projects under harsh environments. In tank protection applications, these anodes are pre-embedded within tank foundations to deliver uniform, comprehensive protective current to tank bottoms. This installation method optimizes current distribution, resolving the challenge of traditional anodes failing to adequately protect entire tank bases.
For reinforced concrete structure protection, expanded-hole titanium mesh anodes have emerged as the most promising anode material in impressed current cathodic protection systems. Their advantages include high current-carrying capacity, reproducible current output, minimal stray current, and efficient installation. Installed on concrete surfaces, these anodes effectively prevent reinforcement corrosion, significantly extending structural lifespan.
Additionally, mesh anode titanium finds extensive application in protecting metal facilities within diverse media such as soil, freshwater, and seawater. In high-temperature, high-salinity environments, by adjusting the composition of its oxide layer, mesh anode titanium adapts to specific corrosion conditions, delivering reliable cathodic protection for pipelines, port facilities, vessels, and more.
The core advantage of mesh anode titanium lies in its extremely low consumption rate and long service life. The precious metal oxide coating exhibits minimal polarization and negligible consumption, enabling operation for over 20 years under standard conditions. Lightweight and easy to transport and install, it can be fabricated into any shape as required by engineering specifications. It delivers uniform current distribution with high reproducibility and minimal stray currents, preventing interference with surrounding metal structures.
However, mesh anode titanium also has limitations. First, its relatively high cost results in significant initial investment. Second, it is sensitive to operating temperature, with designers typically recommending ambient temperatures between 17°C and 80°C. Additionally, installation requires specialized technicians, as construction quality directly impacts system performance, increasing project complexity. For specific projects, the cost of mesh anode titanium may become a key decision factor, particularly in large-scale projects requiring substantial quantities where budget constraints become more pronounced.
