Performance Characteristics of Titanium Cathode Plates and Anode Titanium Plates

Due to the highly reactive thermodynamic properties of titanium and its strong bonding with hydrogen, titanium absorbs hydrogen in a hydrogen-rich environment to a certain level, leading to embrittlement. The hydrogen embrittlement process in titanium is a typical hydride-type hydrogen embrittlement, largely depending on the penetration and diffusion of hydrogen into the titanium matrix. In practical applications, because titanium is often coupled with carbon steel and other metal materials and used for cathodic protection of carbon steel, titanium frequently exists in a cathodic hydrogen evolution environment. Therefore, the study of the performance of titanium during cathodic polarization is necessary.

Electrochemical methods are widely used to study the titanium-hydrogen system due to their simple testing procedures and adaptability to changes in experimental conditions. Methods such as constant current cathodic polarization, constant voltage double-step, constant voltage pulse, and dynamic polarization are commonly employed. Among these, the most used method involves cathodic hydrogen charging using a double-sided electrolytic cell based on the Devanathan-Stachurski device principle.

Research on the cathodic polarization behavior of industrial pure titanium in seawater is conducted using constant current cathodic hydrogen charging and dynamic polarization methods. Titanium's excellent physical and chemical properties, especially its superior corrosion resistance in seawater, have led to its widespread application in seawater desalination, seawater cooling, and other areas. To date, alternating current impedance methods have been used to study the surface performance of titanium during the cathodic process. AC impedance technology has the advantages of being simple, fast, non-destructive to test samples, and providing extensive information. When applied to electrochemical systems, AC impedance measurement can eliminate the influence of electrochemical system instability, allowing online measurement of the electrode surface's polarization resistance and differential capacitance without interrupting the polarization process, thereby obtaining ideal electrode/solution interface information. Hence, attempting to use AC impedance method for this purpose is encouraged.

Characteristics of Anode Titanium Plates:

1. High current, high efficiency, excellent corrosion resistance, long electrode lifespan, and high current density.
2. High catalytic activity. Mox Titanium Anode iridium coating is a low overpotential electrode for oxygen evolution, making it easier to evolve oxygen in the anode oxygen evolution zone. Therefore, during electrolysis, the cell voltage is relatively lower, saving energy. This phenomenon is evident in alkaline copper plating in copper foil post-treatment.
3. Non-polluting. The coated titanium anode is made of noble metal ceramic oxides, which are highly stable and nearly insoluble in any acid or base. The oxide coating is about 8-12μm thick, ensuring that MMO titanium anodes do not pollute the electrolyte.
4. Low maintenance of anodes, increased productivity, and reduced labor costs.

MMO Titanium Anode and titanium MMO Coating Plate are made by coating titanium substrates with noble metal salts such as ruthenium, iridium, and tantalum, followed by high-temperature sintering. They are widely used in electroplating (such as deep hole, high-demand copper, and gold plating in the circuit board industry), electrolytic synthesis, hydrometallurgy, aluminum foil forming, cathodic protection, Wastewater Treatment, sanitation disinfection, etching solution regeneration, and copper recovery. The preparation and application of titanium anodes are quite mature.
