In industrial electroplating applications, the required coated metal is dissolved in the electrolyte, the metal substrate is plated as a negative electrode, and the anode is used as a positive electrode, that is, a complete current transmission cycle is formed. The chemical reaction that occurs in the plating bath at the same time as electroplating is the precipitation of oxygen on the anode surface.

Compared with non-inert anodes, the advantage of titanium anodes is that they can maintain a stable distance between the positive and negative electrodes during their service life. Graphite anodes gradually dissolve in use, resulting in an increased distance between electrodes, while inert titanium anodes ensure stable voltage and product quality.

Due to the catalytic characteristics of platinum group elements, the exchange current density value of the electrode surface is large, the overpotential of oxygen precipitation is low, and a special process is specially used to make a fine-structure oxide film on the surface of titanium, and a large active surface area is obtained in the area of the unit electrode, so it is particularly suitable for high-speed and high current density electroplating production.

In addition to titanium anodes and graphite, lead anodes can also be used in this field. However, when lead anodes dissolve, their reactants can have a negative impact on the environment. These problems can be avoided by using titanium anodes, which have a lower operating voltage and can also save energy.

Compared with conventional lead anodes for electroplating, titanium anodes have the following advantages:

1. Trough low voltage, small energy consumption;

2. The rate of electrode loss is small and the size is stable;

3. The corrosion resistance of the electrode is good, and the insolubility does not pollute the bath liquid, making the performance of the coating more reliable;

4. Titanium anode adopts new materials and structure, which greatly reduces its weight and facilitates daily operation;

5. Long service life, and the matrix can be reused, saving costs.
