Platinised Titanium

Platinised Titanium

Platinised titanium anodes combine the excellent electrochemical characteristics of platinum with the good corrosion qualities of titanium. They are characterised by the following features and provide advantages over soluble anodes and lead anodes:

Platinised Titanium

  • Flexible, application-specific design 
  • Production of complex shape anodes 
  • Energy saving potential
  • Low weight (in particular expanded metal anodes)
  • Long service time even at high current density
  • Dimensional stability, long durability of base material
  • Replating possible 
  • Homogeneous deposition, higher quality of end product

Such anodes consist of a titanium based material in the form of expanded metal, sheet, rod, wire, or pipe. The standard platinum layer thickness is 2 - 5 µm, in case of higher loads layer thickness of up to 20 µm. The lifetime of platinised titanium anodes is in particular dependent on the work medium (electrolyte) and the anodic current (specific current density).

It should not exceed 75 A/dm2. The platinum wear is low under these conditions and the lifetime of the anode is calculable. According to experience, it is approx. 1-4 g platinum per one million ampere hours in fluoride-free chromium baths. In case of specific current densities of over 75 A/dm2 or upon the use of baths containing fluoride, we recommend the use of platinised niobium anodes (see "Platinised Niobium Anodes").

Platinised titanium anodes are very frequently used as expanded metal anodes due to their excellent pratice characteristics (high throwing power, good electrolyte exchange, compact construction, low weight etc.).
