Platinized Titanium & Niobium Anode Dimensionally Stable Anode

Platinised Titanium Anodes are exclusively used in the Hard Chrome Plating application. Platinised Titanium anodes offer numerous benefits. There are Long life, dimensionally stable and easily fabricated into any shape, Homogeneous and long-lasting active surface, Energy savings with shaped anodes and small anode/cathode distances, Reduced environmental burden and reduced maintenance, Mesh anodes provide excellent throwing and can be used at high current densities, Easier handling and replating, Considerations when converting from Lead to Platinised Titanium anodes:

The service life of platinised titanium depends on both the electrolyte matrix and the applied current density. Therefore, in fluoride containing baths and at current densities >75 A/dm2 platinized niobium is recommended in preference to platinised titanium.

Platinized titanium and niobium anodes are completely or partially covered with a fee microns of platinum (usually 2.5 micron). 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 platinised anodes will increase their benefit and maximise their life span.   

Tiaano Customized Platinum plated Anodes or Electrodes are manufactured using the metal of titanium, niobium, tantalum in the production and Pure Platinum Coating. The electrocatalytic functional layers of platinum are used throughout virtually the entire electrochemical industry.

Platinised titanium anodes can only be used successfully in electrolytes which do not attack the titanium base. This excludes use at very low and very high pH values and also Chromium baths containing fluorides.

The service time of the platinised titanium anodes depends on the chemical resistivity of the base metal, the dissolution rate of the deposited platinum in the electrolyte, which in turn depends upon layer morphology, and adhesive qualities, pH, current density and current ripple.

For most applications the dissolution rate is low and the advantages of platinised titanium anodes are far greater than any metal loss. For fluoride-free chromium baths, the platinum consumption will be approximately 1 to 4 g of platinum per million Ah.

Impressed current cathodic protection (ICCP) Platinised anodes have been developed for protection of ship’s hull. Platinised titanium anode are being used in Naval and commercial ships requiring higher current density.

Smooth corrosion-free hulls minimise the power necessary to move ships through the water. Modern vessels, such as the tanker illustrated here in dry dock, are in many cases fitted with impressed current cathodic protection methods for corrosion protection. Platinised titanium counter electrodes used in part of such a system can be seen as four small horizontal strips in line with the propeller shaft.

The principle of impressed current cathodic protection is in connecting an external anode to the material to be protected from corrosion and passing of an external ( impressed ) electrical DC current. These impressed current anodes are also known as dimensionally stable anode or insoluble anodes.

These impressed current anodes are also known as dimensionally stable anode or insoluble anodes. Platinum is an excellent anode material due to its high conductivity and low consumption rate. Due to its high cost, it is not economical to use platinum by itself. So that platinized anodes are produced by electroplating a thin layer of platinum over a lower cost substrate such as titanium, tantalum, niobium or zirconium etc

Water Ionizer Electrodes [Anodes or Cathodes] are available with hanging hook, frame or band in the form of sheet, expanded mesh, pipe, wire, rod and custom built.

Why platinum Anodes in Ionization process:

Most good ionizers on the market use electrodes made of platinum plated titanium. Titanium will not dissolve in your ionized water as the cheaper metals like stainless steel does. The ionizer uses grade 1 titanium (as per ASTM Standard) electrodes to be plated with a good electrical conductor. Stainless steel was used for Water Ionizer electrodes in the late 1980's and was found not be a suitable material because they did not last more than a  few years.

Also Increase anode lifetime without sacrificing quality, Maintain predictable and stable electrode position rates, a low consumption rate that conserves precious platinum, Favorable dimensional stability, Corrosion resistance ensures durability with easy maintainability, Light weight.

Tiaano suggest the platinized Titanium anodes and Platinised Titanium Cathode for water alkaline process because of its advantages like no contamination in water, complex shapes is possible, Long lifetime, Easy maintenance, High dimensional stability and loading capacity, Good corrosion resistance, Low weight, Perfect current and distribution. Anodes and cathodes material will be similar. It will be consume  proper equal voltage in all cells.

Platinised Titanium Anode and Platinised Titanium Cathode in Alkaline Water Machine: The Platinised Titanium electrodes create the ionization, the electrode cell is the heart of an ionizer. It consists of a series of electrodes (plates), each separated by a membrane. The Platinized Titanium Mesh Anodes or perforated Anodes are mostly used, because it has outstanding practical performance, such as strong ability of ionization release, good exchange of electrolyte, close structure and light weight, etc.

Key Benefits of Platinized Titanium Anodes and Platinised Cathodes in Ionisation:-

2)   Corrosion resistance ensures durability with easy maintainability

3)   Light weight, as well as favorable current distribution

4)   High resistance to corrosion

5)   Resistance to oxidation

6)   High electrical conductivity

7)   No contamination in water

Titanium is non-soluble and stable in water. It will last for many years [20, 30 or more] without corroding. Its durability, strength, and non-toxicity make it the choice of material to doctors and medical scientists use for their implanted medical devices such as artificial joints and pacemakers. Also, because it’s so durable and non-magnetic it makes it the best choice of metal to construct a water ionizer electrode.

Platinum is a catalyst, and is needed to speed up the electrolysis. With the water ionizers changing the water so drastically just by passing the water over the electrodes, the ionization process wouldn’t occur without a speeder-upper.

What is Electro Plating? Why platinum Anodes in Electro Plating?

Electroplating involves passing an electric current through a solution called an electrolyte. This is done by dipping two terminals called electrodes into the electrolyte and connecting them into a circuit with a battery or other power supply. The electrodes and electrolyte are made from carefully chosen elements or compounds. When the electricity flows through the circuit they make, the electrolyte splits up and some of the metal atoms it contains are deposited in a thin layer on top of one of the electrodes—it becomes electroplated. 

Our Platinised Titanium Anodes have a proven track record in applications such as Electroplating, Electro Winning or electroextraction, Electrosynthesis, Electrodialysis, Drinking Water electrolysis, Cathodic Protection, Sodium Hypochlorite, HHO Generator, Swimming pool disinfectant, Perchlorate protection, Chlor-alkali industry etc...
