Titanium Anode For Electrolytic Plating

Titanium anode for electrolytic plating is one of the titanium anodes produced by our company . Titanium is a light, strong and corrosion-resistant metal, so it is widely used in electrolytic plating. Its corrosion resistance makes it an ideal material for handling chemically aggressive solutions. Electrolytic plating is a method of plating a layer of metal on the surface of an object through an electrochemical reaction. It is widely used to improve the hardness, corrosion resistance, conductivity and aesthetics of material surfaces. A typical electrolytic plating process includes a cathode, anode and electrolyte.

Titanium anodes are used in electrolysis and electroplating. The insoluble anode is a titanium substrate (mesh, plate, strip, tube, etc.) coated with a noble metal oxide coating with high electrochemical catalytic performance. The oxygen evolution overpotential of the new insoluble titanium anode is also lower than that of the platinum-coated insoluble anode, but its lifespan is more than doubled. It is widely used as anode or auxiliary anode in various electroplating. It can replace traditional lead-based alloy anodes. Under the same conditions, the battery voltage can be reduced and power consumption saved; the insoluble titanium anode has good stability during the electroplating process (electrochemistry, chemistry) and has a long service life. This anode is widely used in nickel plating, copper plating, zinc plating, gold plating, chromium plating and other metal industries.

The size of the electrodes is relatively stable, and the distance between the electrodes will not change during the electrolysis process, ensuring that the electrolysis operation is performed when the cell voltage is stable;

The working voltage is low, so the power consumption is small, and the DC power consumption can be reduced by 10%---20%;

Titanium anodes have a long service life. The metal anodes in the chlor-alkali industry produced by the diaphragm method are resistant to corrosion by chlorine and alkali. The life of the anode reaches more than 5 to 7 years, while the life of the graphite anode is only 8 months;

It can overcome the dissolution problems of graphite anodes and lead anodes, avoid contamination of electrolytes and cathode products, thereby greatly improving the purity of metal products;

Can increase current density and improve electrolysis efficiency;

The oxides of the noble metals iridium and ruthenium are resistant to oxidation, so titanium electrodes have high oxidation resistance;

It can avoid short circuit problems after lead anode deformation, thereby improving work efficiency;

Titanium electrodes are light in weight and can reduce labor intensity compared with graphite anodes and lead anodes;

The shape and fabrication of titanium substrates are easier and can be changed;

The substrate can be reused as long as it is not damaged;

Preparing titanium anodes is one of the key steps in electrolytic plating. Usually, high-purity titanium plates are used to prepare anodes with good surface quality through mechanical processing, polishing and other processes.

In order to improve the surface activity of titanium anodes, surface treatment is often performed. This includes pickling, anodizing and other steps to ensure better performance of the anode in electrolytic plating.

Selection of electrolytes Different electrolytes are suitable for electrolytic plating of different metals. When selecting the electrolyte, consider factors such as the characteristics of the metal and the properties of the required coating to ensure the stability and performance of the electrolyte.

During the electrolytic plating process, the titanium anode is immersed in the electrolyte. After electricity is applied, an oxidation reaction occurs on the anode surface, releasing titanium ions. These ions are deposited on the cathode surface under the action of electric current, forming a metal coating.
