How Electroplating Works (Electrodes - Platinised Cylindrical Anode or Platinised Cylindrical Cathode

Electroplating is the application of electrolytic cells in which a thin layer of metal is deposited onto an electrically conductive surface. A cell consists of two electrodes (conductors), usually made of Titanium with Platinum plating, which are held apart from one another. The electrodes are immersed in an electrolyte (a solution).

When an electric current is turned on, positive ions in the electrolyte move to the negatively charged electrode, called the cathode. Positive ions are atoms with one electron too few. When they reach the cathode, they combine with electrons and lose their positive charge.

At the same time, negatively charged ions move to the positive electrode, called the anode. Negatively charged ions are atoms with one electron too many. When they reach the positive anode, they transfer their electrons to it and lose their negative charge.

Significant factors in Electro Plating Process / Baths

•          The voltage level of current.

•          The temperature and chemical composition of the bath.

•          The current length of time.

•          The distance between the cathode and the anode.

Platinised Titanium Anodes are exclusively used in the Electro Plating Process. Tiaano Electrodes has the technology to platinum titanium substrates in the form of plate, wire, rod, tube, plate and mesh. Furthermore, we have the ability to manufacture complex fabricated anodes. The external surface of all platinised titanium anodes is essentially pure platinum which exhibits all the normal characteristics of the wrought metal as far as corrosion behaviour is concerned. The secret of the quality of a platinised anode lies in the nature of the interface between the platinum and the titanium. It is well known that normal untreated titanium presents a very inert and intractable surface when it comes to applying precious metal coatings. That this problem was overcome to an adequate extent is demonstrated by the wide acceptance of platinised titanium anodes in different industries throughout the world. Although there are still many platinum electroplated anodes produced without an adequate interlayer, they are used for less demanding applications.

What is Electroplating?

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. 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), which is the reverse of the process by which power supply produce electric currents. All these things are examples of electrochemistry: chemical reactions caused by or producing electricity that give scientifically or industrially useful end-products.

Platinised Ionization Electrode:

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.

The Platinum 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 Anode is 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.

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.

Anode Side: Platinum Plated Titanium Anode

Positively charged ions gather at the negative electrode to create reduced water, which concentrates available alkaline minerals, such as calcium, magnesium and potassium from the source water. This alkaline ionized water is drawn for drinking and cooking, through the main stainless steel spout.

Cathode Side: Platinum Plated Titanium Cathode

Negatively charged ions gather at the positive electrode to make oxidized water, which concentrates acid minerals such as nitrates, sulfides, chlorides, and fluorides from the source water. This acid ionized water has a myriad of external uses. It is discharged into the sink.

General Key benefits of Platinum Plated Electrodes:-

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. 

Platinized Anodes (Pt. Anode) are produced by plating platinum (Pt) on a specially treated precious metal (Titanium / Niobium) by means of electro deposition process. They are economical as well as it retains the superior physical and chemical properties. There are many advantages as below.

General advantages for Titanium Anode with Platinum Plating or Platinised Titanium Anode:-

1.         Titanium gives corrosion resistance in most electrolytes. Titanium itself will act as a conductor of current without passing current into the electrolyte.

2.         With the application of a thin layer of platinum onto the titanium surface the current will pass along the titanium and enter the electrolyte through the platinum surface with the exposed surfaces of the titanium remaining inactive. The platinized area of the anode will operate at current densities of up to 100 amperes per square ft. of surface area.

3.         The electrical resistance of titanium is high and where solid rods or plates are used it is essential to design with adequate cross sections of titanium and with the shortest current paths to the platinum surface, thus avoiding high volt drops.

4.         Where long lengths of platinized titanium are required to improve the electrical resistance, titanium is formed over copper and the platinum skip-plated onto the titanium. This provides the most economic installation with the best relationship between current density and volt drop.

5.         It is recommended that rectifier 3 phase AC is used and the voltage between anode and electrolyte should be less than 10 volts.

Platinized titanium anodes are suitable for used in impressed current system for jetties, pipelines protected by deep well ground beds, power stations and water storage tanks. Also the major application of Chlorate & perchlorate production, Eectro-chlorination, Electroplating, Sewage treatment, Electro synthesis, Electro Chlorination, Water Treatment, Water Ionization, Waste Water treatment, Sewage Treatment, Effluent Treatment etc…

Electro winning, also called electroextraction, is the electro deposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electro refining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be electro won.

The metals that can be recovered by this method are copper (Cu), nickel (Ni), zinc (Zn) and cobalt (Co), and used in the recovery of cyanide-based electrolytes of gold (Au), silver (Ag), copper (Cu), zinc (Zn) and cadmium (Cd) - cyanide is electrochemically destroyed, due to the enhanced anode efficiency. Different metals plate out at different voltages so application if the different voltages will allow all metals to be recovered from a mixed metal effluent.
