Platinised anodes are manufactured with a titanium or niobium base structure, in the form of either expanded metal, sheet, rod, wire or tube. A thin coating of platinum or layer of platinum between 2 to 5 microns thick is maintained on these various shaped anodes made-ready for metal finishing at plating baths. These platinum coated-or-plated anodes posses the electro-chemical properties of platinum and behaves like platinum metal. Platinized plating anodes coating/ layer thickness ranges from minimum 1.5 µ & max 20 µ.
Platinised titanium anodes (Pt-Ti anode)
Platinised titanium (platinum coated/ layered titanium) anodes are recommended for use in the following electrolytic processes
Precious metal electroplating - e.g. Au, Pt, Pd, Rh and Ru baths Non-ferrous metal electroplating - e.g. Ni, Cu, Sn, Zn and non-fluoride Cr baths.
* Platinised titanium anodes are not recommended for Chromium plating baths containing fluorides or F-content.
Platinised Niobium anodes (Pt-Nb anode)
Platinised niobium (platinum coated/ layered Niobium-Nb) anodes are recommended for use in the following electrolytic processes
Chrome plating baths with F-content.
Cathodic Protection against seawater environment
Advantages
Long operating life; maintenance-free.
Economical (low platinum requirements for layering / coating)
High dimensional stability and load resistance.
Good current distribution.
High corrosion resistance.
Light weight
