Introduction to titanium (titanium anode, cathode roller) surface brush plating technology
Characteristics of Titanium Electrode and Its Role in Electrochemical Industry
​
In the conventional electrochemical industry, graphite, platinum (or platinized titanium electrodes), lead and alloys thereof are commonly used as electrodes (anode, or cathode) materials. Since Beer developed the titanium-based ruthenium dioxide coated anode for the first time, the electrochemical DSA (Dimensinal Stable Anode) material has been gradually developed into a new electrode material for surface catalytic modification using titanium as a substrate.
Whether it is used as an anode material or a cathode material, titanium is required to have good electronic conductivity with a connection portion of an electron conductor (conductive row). However, titanium is an easily passive metal. In atmosphere, even in most acidic aqueous solutions (except for fluorine-containing acids), the surface of titanium is highly prone to form an oxide film which has very poor electrical conductivity. Due to this reason, the surface contact resistance of titanium is increased. This results in reduced energy consumption, reduced anode life, altered cell pressure, and even changes in the type of electrode reaction.
Therefore, in the production process of the titanium electrode, it is necessary to plate a metal surface layer (platinum, silver, tin, nickel, etc.) with good conductivity and not passivation on the lap joint surface of the titanium electrode and the bus bar.

Challenges existing in titanium plating (plating, brush plating, vacuum plating)
​
In order to ensure the bonding force between the plating layer and the substrate, when the metal plating layer is prepared by the electrodeposition method, it is necessary to carry out appropriate pre-plating treatment to ensure that the surface to be plated of the metal is free from oil, rust and oxide film. However, for titanium, it is very difficult to completely remove the oxide film on the surface. Therefore, electroplating on titanium has always been an urgent problem to be solved. The founder of the company has been engaged in the application research of titanium-plated metallization on titanium for a very long time. He has successfully carried out applications and promotions of titanium-based cathode roll silver plating, titanium-based anode bath platinum plating, titanium-based cathode roll nickel plating, titanium-based electrolytic anode tin plating, and titanium alloy downhole tool copper plating technologies. These technologies have greatly solved the challenge of brush plating on the surface of titanium.
