Advantages of MMO Mesh Anode
MMO mesh anode is an auxiliary anode used in electrochemical and cathodic protection systems. Its core is to coat a layer of mixed metal oxide coating with electrocatalytic activity on the titanium-based mesh, such as ruthenium (Ru), iridium (Ir), titanium (Ti), tantalum (Ta), etc. These metal oxides are evenly coated on the titanium-based mesh through a special coating process to form a thin film with electrocatalytic activity. The composition and thickness of the coating will directly affect the performance of the anode, such as conductivity, catalytic activity, service life, etc. Different specifications of titanium-based mesh, such as mesh size, wire diameter, etc., can be selected according to specific application requirements.
- High Reactivity And Efficiency
One of the biggest advantages of the mesh structure is that it significantly increases the surface area. The surface area of the anode is a key factor in determining the reaction rate and efficiency.
- Promote Mass Transfer Process
The open pore structure of the MMO mesh anode forms countless tiny channels, providing a convenient path for the transmission of ions. Maintaining a high current efficiency reduces energy consumption.
- Uniform Current Conduction
The mesh structure of the MMO mesh anode has good conductivity and unique geometry, which can evenly distribute the current over the entire anode surface. The consistency of the results is guaranteed.
- Reduce Risks
The MMO mesh anode ensures that the current is evenly applied to the protected metal surface, so that its potential tends to be consistent, thereby effectively suppressing the risk of local corrosion.
- Good Mechanical Properties
The titanium mesh matrix of the MMO mesh anode has high strength and toughness, and can withstand a certain degree of external force impact and tensile deformation without cracking or damage.
- Easy to Install
The mesh structure makes it lightweight and flexible, suitable for equipment of different shapes and sizes. It can be bent, cut and spliced according to actual needs to achieve flexible installation
Custom Manufacturing MMO Anode Services
The titanium-based mesh used by Wstitanium to manufacture MMO mesh anodes is usually made of industrial pure titanium with a purity of more than 99%. High-purity titanium has better corrosion resistance and processing performance, and can provide a more stable adhesion basis for mixed metal oxide coatings.
Size Specifications
The specifications of the titanium-based mesh, such as mesh size, wire diameter, etc., will be selected according to different application scenarios and design requirements. Generally speaking, for applications that require higher current distribution uniformity, titanium-based meshes with smaller meshes and finer wire diameters will be selected. For applications that need to withstand greater mechanical stress, titanium-based meshes with larger meshes and thicker wire diameters will be selected. For example, in the cathodic protection of the tank bottom plate, titanium-based meshes with mesh sizes of 10mm×10mm – 20mm×20mm and wire diameters of 0.8mm – 1.2mm are usually selected.

Manufacturing technology
Removing impurities: Before applying the mixed metal oxide coating, the titanium-based mesh needs to be thoroughly cleaned to remove impurities such as oil, dust, and oxides on the surface. Usually, a combination of chemical cleaning and ultrasonic cleaning is used. First, organic solvents (such as acetone, ethanol, etc.) are used to remove surface oil, and then acidic solutions (such as hydrochloric acid, sulfuric acid, etc.) are used to remove surface oxides, and finally rinsed with deionized water. The surface of the titanium-based mesh after cleaning should be free of obvious impurities and stains to ensure good adhesion between the coating and the substrate.
Etching: Etching is one of the key steps in surface pretreatment. Through chemical etching or electrochemical etching, a microscopic rough structure is formed on the surface of the titanium-based mesh, increasing the contact area between the coating and the substrate and improving the adhesion of the coating. Commonly used etching solutions include a mixed solution of hydrofluoric acid (HF) and nitric acid (HNO₃), which is used to etch the titanium-based mesh under certain temperature and time conditions. The surface of the titanium-based mesh after etching should show a uniform microscopic roughness, and the etching effect can be evaluated by means of detection such as scanning electron microscopy (SEM).
Coating: Thermal decomposition is one of the commonly used coating processes for Wstitanium to manufacture MMO mesh anodes. First, the precursor solution of the mixed metal oxide (such as a metal salt solution) is evenly coated on the titanium-based mesh after surface pretreatment, which can be sprayed, dipped, brushed, etc. The coated titanium-based mesh is then thermally decomposed in a high-temperature furnace, generally at a temperature between 400℃ and 600℃. During the thermal decomposition process, the metal salt gradually decomposes into metal oxides and forms a chemical bond with the surface of the titanium-based mesh, thereby forming a strong mixed metal oxide coating. The thermal decomposition method can accurately control the composition and thickness of the coating, and the desired coating properties can be obtained through multiple coatings and thermal decompositions.
Quality Control
During the manufacturing process, a non-contact coating thickness gauge is used to monitor the coating thickness of the MMO mesh anode in real time. Depending on different application requirements, the coating thickness is generally controlled between a few microns and tens of microns. The composition of the mixed metal oxide coating is analyzed regularly, and the content and proportion of various metal elements in the coating are detected using advanced analytical instruments such as X-ray fluorescence spectrometer (XRF) and inductively coupled plasma mass spectrometer (ICP-MS). By strictly controlling the coating composition, the performance of the MMO mesh anode can be guaranteed to be stable and reliable.
MMO mesh anodes have achieved good results in marine engineering, sewage treatment, electroplating and other industries, providing strong support for the development of related industries. With the continuous advancement and innovation of technology, MMO mesh anodes are expected to be applied and promoted in more fields, further promote the development of electrochemical engineering technology, and make greater contributions to the realization of sustainable industrial development.
