PLATINISED TITANIUM ANODE BENEFITS AND PROCESS IMPROVEMENTS OVER LEAD ANODE IN HARD CHROME PLATING
The change from the lead anode to platinised the titanium anode was promoted by the introduction of high efficiency fluoride free baths. Which attacked lead anodes more severely than traditional hard chrome plating chemistries. Initially lead rod anodes were replaced with titanium rod anodes, which had a copper or aluminum core for high current applications, and over time further advantages platinised titanium anode have been recognized.
Platinised Titanium Anodes:
In order to utilize platinum’s exceptional conductive properties and corrosion resistance still remain economical & anodes are proceed by electro plating a very thin layer (typically 2-5MM) of platinum onto a specially treated activated substrate such as titanium or niobium.
The service life of platinised titanium depends on both electrolyte matrix and the applied current density. Therefore, in fluoride containing baths and at current densities >75 A/dm2 platinised niobium is recommended in preference to platinised titanium.
