Description of Pt/Nb Mesh Electrode
Our platinum-coated niobium anode is manufactured using a precision electroplating process, ensuring the niobium substrate—specially treated for enhanced adhesion—is fully or partially coated with a uniform layer of high-purity platinum. The surface appears silver-white with a fine, durable coating, offering strong platinum-to-niobium bonding, high current output, excellent corrosion resistance, and an extended service life. This platinized niobium electrode is ideal for electroplating, cathodic protection, and water treatment, and is particularly suited for fluoride-containing electrolytes, such as those used in hard chrome plating of piston rings, valves, and other precision components.

FAQ platinum niobium mesh electrode
What is platinum-coated niobium mesh?
A platinum-coated niobium mesh is a high-performance electrode made from a niobium (Nb) substrate electroplated or PVD-coated with a thin layer of platinum (Pt). It combines niobium’s corrosion resistance with platinum’s superior conductivity, making it ideal for electroplating, water treatment, and cathodic protection.
What applications is it best suited for?
Hard chrome plating (e.g., piston rings, hydraulic rods)
Precious metal electroplating (gold, rhodium, silver)
Seawater cathodic protection (offshore platforms, ship hulls)
Ozone generation (water purification systems)
Is it compatible with fluoride solutions?
Yes! Pt/Nb mesh is one of the few anodes that resist:
- Hydrofluoric acid (HF)
- Fluoroborate baths (e.g., hard chrome plating electrolytes)
