In the industrial electroplating application industry,the required coating metal dissolves in the electrolyte,and the plated metal substrate serves as the negative electrode,while the anode serves as the positive electrode,forming a complete current transmission cycle.The chemical reaction that occurs simultaneously with electroplating in the plating tank 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 within their service life.Graphite anodes gradually dissolve during use,leading to an increase in the distance between electrodes,while inert titanium anodes can ensure stable voltage and product quality.
Due to the catalytic properties of platinum group elements,the exchange current density on the electrode surface is high,the overpotential of oxygen evolution is low,and a special process is used to create a microstructure oxide film on the titanium surface,which obtains a large active surface area per unit electrode area.Therefore,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 the lead anode dissolves,its reactants can have a negative impact on the environment.By using titanium anodes,these problems can be avoided.The working voltage of oxygen evolving titanium anodes is lower,which can also save energy.
Compared with conventional lead anodes used in electroplating,titanium anodes mainly have the following advantages:
1.Low slot voltage and low energy consumption;
2.The rate of electrode loss is small and the size is stable;
3.The electrode has good corrosion resistance and insolubility,which does not pollute the tank solution,making the performance of the coating more reliable;
4.The titanium anode adopts new materials and structures,greatly reducing its weight and facilitating daily operation;
5.Long service life and reusable substrate,saving costs.
