Due to titanium's very positive thermodynamic properties and strong binding force with hydrogen, titanium becomes hydrogen absorbent when it absorbs hydrogen in a hydrogen-generating medium to a certain extent. . It depends on the penetration and diffusion of hydrogen in the titanium matrix. In practical application, since most titanium is used together with metallic materials such as carbon steel, it is necessary to perform cathodic protection on carbon steel. In this way, the titanium anode will normally be in the environment of the hydrogen cathode evolution, so it is necessary to study the properties of titanium during cathode polarization.

　Electrochemical methods have the advantage of being widely used in the study of titanium-hydrogen systems due to their simple test sequences and their adaptability to changes in experimental conditions. For example, the constant current cathode biasing method, the constant voltage two-step method, the constant voltage pulse method, the dynamic polarization method, etc., and the commonly applied method is the use of electrolytic cells. two sides to charge hydrogen for the cathode according to the principle of Devanathan -Stachurski device.

　　Titanium anode manufacturers studied the cathode polarization behavior of industrially pure titanium in seawater. Constant current cathode hydrogen charging method and dynamic polarization method, especially the excellent corrosion resistance in seawater, titanium is ultimately due to its excellent physical and chemical properties. Desalination in seawater, seawater cooling and other aspects have been widely used. Until now, the AC impedance method has been used to study the surface performance of titanium in the cathode process. AC impedance technology has the advantages of simple, fast, no damage to the test specimen and the amount of information. large in use. In electrochemical systems, the AC Impedance Measurement Procedure can eliminate the effect of electrochemical system instability and can measure the polarization resistance and differential capacitance of the electrode surface on-line without interrupts the polarization process and it is an ideal method to obtain information on the electrode/solution interface. Therefore, try to use the link-boosted AC Impedance Method.

Features of titanium anode plate:

　　1. High current, high efficiency, excellent corrosion resistance, long electrode life and high current density;

　　2. High catalytic activity, titanium anode with iridium coating is a low oxygen evolution overvoltage electrode, which is easier for oxygen evolution in the anode oxygen evolution region. Therefore, the cell pressure during electrolysis is also relatively low, which saves electricity. This phenomenon was clearly demonstrated during the copper foil treatment after alkaline copper plating;

　　3. Non-polluting, coated titanium anode is a precious metal ceramic oxide, which is quite stable oxide, almost insoluble in any acid and alkali, and the oxide coating is about 8-12 μm, so the MMO titanium anode will not contaminate the electrolyte solution;

　　4. Less anode maintenance, higher productivity and lower labor costs.

　　Titanium coated anode plate is made of ruthenium, iridium, tantalum and other precious metal salts coated on titanium and sintered at high temperature. Synthesis, hydraulic metallurgy, aluminum foil generation, cathode protection, wastewater treatment, cleaning and disinfection, etching solution regeneration and copper recovery, etc., the preparation and application of titanium anodes has been quite good. proficient.
