Platinized Titanium & Niobium Anode Dimensionally Stable Anode

Platinized anodes are manufactured with a titanium or niobium base structure, in the form of either expanded metal, sheet, rod, wire or tube. A thin plating of platinum between 2 to 5 microns thick is maintained on these various shaped anodes made-ready for electro plating at plating baths. These platinum plated anodes possess the electro chemical properties of platinum and behaves like pure platinum metal. Platinized plating anodes coating/ layer thickness ranges from minimum 1.5 micron to max 20 micron.

Tiaano Platinised Titanium Anode for Hard Chrome Plating. Current hard chromium plating processes are principally based on chromic acid and sulfuric acid. The nature of chrome electroplating bath can impact the longevity of the anodes. In particular, free fluoride ions; it can attack the metals of the anode and cause corrosion. 

Lead tin alloy anodes are commonly used for hard chrome plating. But the sludge of lead chromate is usually formed on the bottom of the plating tank. As a soft metal, lead alloy anode is easily deform or bend. It affects the current density and result in uneven plating thickness and may cause short circuit.

Platinized titanium anode is a good option in hard chrome plating. It reduces the amount of hazardous lead sludge generation, is dimensional stability, resulting in a more stable, homogeneous, and consistent-thickness plating process. Platinized anodes are much more flexible in shaping and dimensioning and can be designed according to the shapes of the work pieces to be plated.

Tiaano employs titanium tube as substrate, since it produces uniform current density and excellent plating results. It also enables gases to escape more effectively and increase the movement of the electrolyte. Also give a higher coating current density and smaller distances between the anode and the cathode.

For Plating, Tiaano has designed a high-temperature electrolysis method for platinum plating. The purity of the plating is at 99.99 percent. The ductility, adhesion and corrosion resistance of the platinum plating are considerably better, while the internal stresses are kept to a minimum. The plating or coating thickness distribution is much more uniform, because of the dimensional stability of the anodes.

Tiaano Platinized Titanium Mesh Anodes are most suitable for Semiconductor and electronics Industries for plating of precious metals like gold, platinum, rhodium and copper. This process called electroplating. Also known as electro deposition. This process deposits a thin layer of metal on the surface of a work part referred to as the substrate. Semiconductors are the footing of the electronics industry. These partially conductive products include transistors, chips and other electronic control parts, and are integral to electronic equipment from mobile phones to cars and robots.

Platinum Plating on Semiconductors:-

Platinum is an extremely rare and expensive material, even more expensive than gold. However, platinum is an exceptionally smooth-surfaced and durable material that protects against corrosion.

How does plating on semiconductors using Platinised Anodes?

•          The plating metal is connected to the positively charged electrode of an electrical circuit. This electrode is called the anode. (Platinum Plated Titanium Anode)

•          The work part is placed at the negatively charged electrode, called the cathode.

•          Both the plating metal and the substrate are immersed in an electrolytic solution called a bath.

•          After submersion, a DC current is supplied to the anode (Platinum Plated Titanium Anode). Oxidizing the atoms of the plating metal and dissolving them into the bath. At the cathode, the negative charge reduces the atoms, causing them to plate the substrate.

This general process defines most electroplating. However, semiconductor electroplating is much smaller in scale than the average electroplating processes. The chips in question are often less than an inch in diameter, and the circuits inside them consist of miniscule wires. Any errors, such as breakage or the addition of dust particles to the semiconductor, can result in a defective product. As a result, semiconductor electroplating involves a few extra precautions and considerations in order to ensure the quality of the finished product.

Platinized titanium anode is a layer of platinum on titanium substrate. It is lasting, non-consumable and insoluble in the electrolyte, it is widely used in electroforming, electroplating and hard chrome plating field.

Tiaano manufactures platinized titanium anode by adopting Electro deposition process to get a dense wear-resistant layer of platinum coating. The anode surface is changed to improve adhesion of platinum and to significantly improve uniformity of coating or plating thickness. Also reduce the plating porosity imparting greater acid resistance to the anode. This platinum plated titanium anode can be fabricated into Plate, rod, sheet, mesh and other customized shape to meet the special needs.

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

Platinised anodes consist of a titanium base or 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).

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 platinized titanium anodes are far greater than any metal loss.

Advantages of platinised Titanium Anode:-

•          Long operating life, maintenance-free.

•          Economical due to low platinum requirements.
