Tiaano, Platinised Titanium Electrodes are most suitable for electro plating of precious metals like gold, platinum, palladium, chromium, nickel, rhodium and copper etc…

Platinised titanium anodes / Niobium Anodes consist of a titanium base / Niobium base, in the form of either expanded mesh, sheet, rod, wire or tube with a plating of platinum between 2 to 5 microns thick and purity of platinum is 99.99%. They possess the electrochemical properties of platinum. The titanium used is 99.9% pure as established by ASTM (American Society of Metal).

Platinised titanium and niobium Electrodes are completely or partially covered with a fee microns of platinum (usually 2.5µm). Where the platinum is consumed after years of use, the underlying titanium or niobium passivates and the bath voltage rises at constant current operation. The base metals are not attacked at the usual operational voltages, in fluoride free chromium baths.

For most applications the platinum wear rate is very low and the corresponding anode life time high. In sulphuric acid chromium baths the platinum consumption is between 1g and 4g platinum per million amp hours. Careful design of the platinized anodes will increase their benefit and maximize their life span.  

Platinized titanium Electrodes / Anodes provide a cost effective replacement for lead anodes in hard chromium plating. They provide superior quality deposition and consistency resulting in increased productivity and throughput. Cost benefit analysis demonstrates that the higher initial investment in this technology can be recouped within a short period of time.
