Why platinum Anodes in Electro Plating process: 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, as well as favorable current distribution in electroplating.

Dense crystalline layer structure and thereby good mechanical properties; Even metal distribution of the platinum layer and optimal adhesion of the titanium mesh; Long lasting (approx. 8 g platinum per 1 million Ah are removed per bath) and dimensionally stable; the base material or substrate is reusable after re-plating.  No maintenance of anodes necessary; Constant conductivity of the anodes; Very short distance from the electrode to the articles (cylinder - 4-6 cm.).  Chrome plating is essentially faster and a chrome layer is very even (cause an even current distribution and enable the use of a higher current density), due to the constant electrolyte flow through anode mesh.

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 batteries 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.

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.

Customized Electrode Production with Pure Platinum Plating on Titanium or Niobium

Platinum-titanium insoluble anodes are based on titanium metal as anodes in the form of sheets, plates, rods, filaments, and tubes. The thickness of the standard platinum layer is 2-5µm. Under higher requirements, the thickness of the platinum layer can reach 20µm. The service life of the platinum-plated titanium anode depends on the working medium (electrolyte) and the current strength (current density) of the anode. The current density should not exceed 75A / dm2. Below this value, the wear of the platinum layer is very small, and the service life of the anode can also be estimated. According to experience, the wear of the platinum layer is about 1-4 grams per million amp-hours in a fluorine-free chromium plating solution.

Titanium anode is mainly used in industrial production such as chlor-alkali and sodium hypochlorite, electrolytic synthesis of organic compounds, sewage treatment, seawater desalination, electrolysis of dilute brine, anode for sodium hypochlorite, anode for sodium chloride electrolysis, disinfection of tap water, series of electrode products for sewage treatment, seawater desalination Electrodes, elimination of plankton in industrial circulating water, etc. The main categories are: platinum titanium electrode, titanium electrode, super titanium electrode, noble metal plating electrode group.

What is Electroplating?

Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes. The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode. Electroplating is often applied in the electrical oxidation of anions on a solid substrate like the formation of silver chloride on silver wire to form silver chloride electrodes.

Electroplating is majorly applied to modify the surface features of an object (e.g corrosion protection, lubricity, abrasion), but the process can also be used to build thickness or make objects by electroforming.

The Anode and Cathode

In electroplating practice, the current is usually introduced from an external source and the anode (Platinised Anode) is the positive electrode and cathode is a negative electrode. The cathode is the electrode where the electrochemical reduction reaction occurs. The anode (Platinised Anode) is that where the electrochemical oxidation reaction occurs.

The electroplating process uses an anode (Platinised Anode) and a cathode. In electroplating, the metal dissolved from the anode can be plated onto the cathode. The anode is provided with direct current, oxidizing and dissolving its metal atoms in the electrolyte solution. At the cathode, the dissolved metal ions are decreased and the metal is placed on the product. That is called Electro Plating process.

Platinum is a precious metal having very good physical and chemical properties. Tiaano manufacturing and supplying platinized anodes are widely used for electroplating and electro winning industrial applications. Electroplating is used in a variety of industries for coating metal objects with a thin layer of a different metal. This electrochemical process requires anodes. There are as many types of anode compositions as there are applications. Platinized Titanium and platinised Niobium Electroplating anodes offer numerous benefits.

Electroplating anodes are used to create products in many industries, including the hydraulic industry. The most common uses for electroplated products are chrome-plated oil pump auger flights, hydraulic cylinders, conveyor flights, sheets and tanks where it would be impractical or too expensive to make the item entirely out of the plating metal.

What is Electroplating?

Electroplating is used to coat certain metals with a thin layer of a pure metal, like silver or gold, copper, zinc or any of several alloys. During the process, an electric current passes through a solution known as an electrolyte. The composition of the electrolyte depends on the desired coating. The item being electroplated (cathode) is immersed into the electrolyte solution, as is the plating anode. 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.
