Products Description
Platinum plated titanium mesh anode is a high-performance insoluble anode manufactured by coating a layer of platinum onto a titanium mesh substrate. It combines the excellent corrosion resistance of titanium with the superior electrochemical performance of platinum, offering low resistance, high catalytic activity, dimensional stability, and long service life.
The expanded mesh geometry significantly increases the effective active surface area, allowing for optimal electrolyte circulation and uniform current distribution. This makes it an ideal choice for high-end applications demanding reliable performance in aggressive chemical environments.

Products Features
Exceptional Electrocatalytic Activity: Coated with ≥ 99.99% pure platinum, delivering extremely low overpotential for both oxygen and hydrogen evolution reactions.
Superior Dimensional Stability (DSA): Unlike consumable anodes (e.g., lead or graphite), titanium retains its exact geometry over its entire operational lifespan, ensuring consistent plating and electrolysis quality.
High Corrosion Resistance: Forms a robust passivating oxide layer (TiO₂) on the substrate, making it highly resistant to heavily acidic, alkaline, and chloride-rich environments.
Cost-Effective & Recoatable: Once the platinum layer is depleted, the titanium substrate can be stripped, cleaned, and replated, drastically reducing long-term replacement costs.
Optimized Mesh Structure: Promotes rapid gas bubble release, minimizes electrical resistance, and ensures an exceptionally uniform current density distribution (up to 8,000 A/m²).
Products Process
-
Platinum-coated titanium anode mesh is produced by brush plating,which is a slotless electroplating process.
-
This technology allows brush plating on complex or irregular surfaces,which is not possible with tank plating.
-
The brush plating process offers several advantages,including high efficiency,low waste, and ease of use.
-
In addition,it is suitable for small scale plating and repair work.

Surface treatment: First, the surface of the substrate needs to be treated, including cleaning, degreasing, pickling and other processes to ensure that the surface of the substrate is clean and free of oil and oxides.
Plating solution preparation: Prepare the plating solution according to the composition and thickness of the required coating. The plating solution of gold-platinum anode brush plating and sintering process mainly includes hydrochloric acid solution containing gold, platinum and gold.
Electrolytic deposition: The surface-treated substrate is immersed in the plating solution, and metal ions are deposited on the surface of the substrate through electrolysis. During the electrolysis process, parameters such as current, temperature and time need to be controlled to ensure the uniformity and quality of the coating.
Sintering treatment: The substrate that has been electrolytically deposited requires high-temperature sintering treatment, usually above 1000°. During the sintering process, metal ions react chemically with the substrate to form a dense metal bonding layer.
Finishing process: After sintering, the coating needs to be polished, cleaned and other processes to improve the finish and surface quality.

Plating is a process for coating metal surfaces. Metal materials such as platinum and gold are evenly plated on the surface of the substrate through mechanical brushing,electrolytic deposition, etc.After high-temperature sintering treatment, the metal material forms a strong bond with the surface of the base material,thereby improving the hardness and corrosion resistance of the material.
Plating doesn't require a power source,can be performed in a smaller working area,can be used on objects with complex surface textures or very irregular shapes,and has good adhesion and uniform coating thickness.
Plating has strong adhesion and can be used on objects with complex surface textures and irregular shapes.At the same time,the coating thickness of brush plating is also thinner than electroplating,so it is suitable for use in some fields that require coating thickness.The plating process is relatively environmentally friendly and low cost.
