Platinum Plated Titanium Disc Anode and Half Disc Anode for Electro Plating

Platinum is a precious metal having very good physical and chemical properties such as high corrosion resistance, thermal conductivity and catalytic nature. The Platinum Coating delivers excellent performance and a long service life. The life time of platinised titanium anodes is in particular dependent on the work medium (electrolyte) and the anodic current (specific current density). 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.

Different Types of Platinised Titanium Anodes for Electro Plating Industry

Electroplating anodes are used to create products in many industries. All kinds of metals can be plated in this way, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum, and lead. Electroplating is very similar to electrolysis (using electricity to split up a chemical solution).

Brief overview of Electro Plating process:-

The two are then connected to an electrical current source, by connecting the positive end to the plating anode and the negative to the item being to be plated. Once current flows through the system positively charged metal ions become attracted to the negatively charged item, thereby coating the item with the desired finish.

Key Benefits of Platinized Titanium Anodes in Electroplating:-

FRP Insulated Platinised Titanium Strip Anode for Cathodic Protection (ICCP)

Tiaano manufacture and supplier of FRP insulated Platinised Titanium Strip Anodes for ship hull protection. Effective cathodic protection guarantees corrosion free existence. Providing the structure is maintained at a potential of –0.8 volts, no loss of metal will occur at all during the life of the structure.

How does corrosion take place in ships?

Ships are made of steel; whose main component is iron. Iron is an electrochemically positive element, i.e., it has a tendency to give up electrons to become a free ion. Sea water is composed of oxygen and hydrogen, and it produces electrochemically negative hydroxyl ions which can accept the electrons given by Iron. This way the Iron ions combine with the hydroxyl ions of water to form Iron Hydroxide. This is called the oxidization of Iron, and this oxide is what we call as the brown color rust.

Cathodic protection is a mechanism which is employed to protect the ship’s surface from corrosion.

Advantage of our Platinised Titanium Anode - Ship Hull Protection:-

• Increased life of rudders, shafts, struts and propellers as well as other underwater

Platinum Plated Sheet Anode for Electro Plating Application

Platinised titanium anodes combine the excellent electrochemical characteristics of platinum with the good corrosion qualities of titanium.  This anode is designed for Electro Plating application. They are characterised by the following features and advantages.

•          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

•          Higher quality of end product

Such anodes consist of a titanium based material in the form of expanded mesh, sheet, rod, wire, or pipe. The standard platinum layer thickness is 2 - 5 micron, in case of higher loads layer thickness of up to 20 micron. 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.

 

Platinised Titanium Anode with Electrical Connector or Hook for Electrolysis

Platinum is widely used as electrodes in many industries, having special chemical & physical properties like high corrosion resistance, thermal conductivity and catalytic nature.  Being a very expensive metal, instead of using solid form, platinum is deposited on the surface of titanium or niobium, occasionally on molybdenum by micron level layer.

Electrodes [Anodes or Cathodes] are available with hanging hook, frame or band in the form of sheet, mesh, pipe, wire, rod and custom built.  Platinised titanium anode is used in electrolytes having no fluoride. Platinised niobium anodes are used in electrolytes having fluoride, where we need better conduction (its conductivity is three times of titanium)  and  also it is suitable for Sulphuric acid chromium plating bath operated at current density greater than 75A / dm².

Platinised Titanium Sheet and Mesh Anode and Titanium Connecting Fasteners

Tiaano manufacturing different sizes and Shapes of platinised Titanium Electrodes for water ionizers. The essential components of the ionization chamber are its two collecting electrodes, (the anode and cathode) the anode is positively charged with respect to the cathode.

A water ionizer works on the simple principle of electrolysis. Any type of water ionizer has two electrodes put into a container having two chambers separated by a semi-permeable membrane. The two electrodes - positive and negative, are put into two separate chambers and the current is passed through them. Ionization process takes place on passing of the current through the electrodes. The dissolved minerals get attracted either to the positive or negative electrode, therefore one of the chambers will have acidic water while the other will have alkaline water. The alkaline water is for drinking purpose, whereas the acidic water is for disinfecting or sterilizing purposes.

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.

         

Benefits of Platinised Titanium Anodes over Lead Anodes for Hard Chromium Plating

Long life, dimensionally stable and easily fabricated into any shape:  When used in the plating process, dimension of the lead anodes are changing due to the loss of the lead oxide which is formed on  the anode during operation - it leads  surface area is getting collapsed . Also larger lead anodes can lengthen under their own weight.  Whereas titanium anodes are dimensionally stable throughout their operating life and can easily be manufactured, even in complex shapes and lengths, up to 4m. Consequently, shaped anodes can be manufactured very accurately to allow consistent plating to small tolerances, often making a further honing step unnecessary.

Homogeneous and long-lasting active surface: When lead anodes are not in use the lead oxide layers change to lead sulphate and lead chromate, which are not good conductors and consequently do not perform consistently. Platinised titanium anodes operated correctly, remain deposit free and therefore perform constantly well throughout the whole anode life.

Energy savings with shaped anodes and small anode/cathode distances: Small electrode gaps reduce electrical resistance losses in the plating bath and produce energy savings. In the case of lead anodes, which cannot be formed as accurately as a mesh, resistance losses result in bath heating, requiring further energy for cooling. Therefore, platinised titanium anodes can provide energy savings both in heating and cooling which, in turn, allows the plating chemistry to be easier to manage and maintain.

Reduced environmental burden and reduced maintenance: No chemical cleaning or brushing of passivated areas is necessary. Bath life is increased as there is no formation of lead sludge - lead anodes produce about 3g of lead sludge for every 1kg of chromium deposited in sulphuric acid type baths and even higher in other baths. Furthermore, the reduced resistance losses and subsequent need for cooling allow for easier maintenance and control of the plating chemistry.

Mesh anodes provide excellent throwing and can be used at high current densities: In electrolysis, corners and edges are preferred reaction sites; an expanded mesh has edges evenly distributed across the anode surface, thus producing uniform current density and excellent plating results. Large area mesh anodes improve throwing power and the mesh structure allows good solution movement and electrolyte exchange and plating with high current densities.

Easier handling and recoating: Positioning of lead anodes for optimising chrome plating is often awkward due to their weight, whereas spot welded or bolted mesh anodes are very light by comparison and allow safer and easier handling. Furthermore, they can be easily removed and / or replaced whenever necessary. This often allows a re-use of expensive anode materials and designs, and reduces operational costs. 

Considerations when converting from Lead to Platinised Titanium anodes:

Where platinised titanium anodes are used as a replacement for lead anodes consideration must be given to several factors to ensure that the technology is utilised to its full potential – a change in plating process is necessary and, as such, the whole plating set-up and its costs need to be considered to maximise the return on the investment in these anodes.

Consideration should be given to:-

Thorough cleaning of the plating tank and associated equipment with an adjustment of the residual lead concentration.

Bath/Electrolyte composition and operating conditions.

Current Density and operating Voltage.

Anode design.

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 platinised niobium is recommended in preference to platinised titanium.

Platinised titanium and niobium anodes 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 platinised anodes will increase their benefit and maximise their life span.  

Summary: Platinised titanium 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.

 

Platinised Titanium Anode and Platinised Titanium Cathode or Titanium Cathode for Water Ioniser or Alkaline Water Application

Tiaano manufacturing different sizes and Shapes of platinum or platinised anode for water ionizers. Water Ionizer Electrodes [Anodes or Cathodes] are available with hanging hook, frame or band in the form of sheet, expanded mesh, pipe,  rod and custom built. 

The best water to drink is alkalized or ionized water, which is produced by running normal tap water over a positive (platinized anode) and a negative (platinised cathode) electrode. This creates positive and negative ions in the water that are then separated creating two different waters, one that is alkaline and one that is acidic.

Alkaline water is for flushing out internal toxins, scavenging free radicals, and oxygenating the body. Acid water, which is really a by-product of ionizing water, can be used externally for cleansing the skin, cleaning any surface and feeding your plants.
