3. http://indacocoats.com/ • Anodizing is a process, where the surface of the metal is coated with the oxidised metal. In the process, the metal is dipped into a tank filled with electrolyte solution and electric current is passed through the solution. The electric current causes the metal to oxide. The metal to be anodized, act as an anode and a cathode in the form of lead, is placed into the tank. • Anodizing forms thick layer of metal oxide on the surface of the metal. This layer helps in wear and tear of the metal, gives attractive finishing to the metal, allows the metal to survive longer in an unfavourable condition for metal like marine.

4. There are very few metals that can be anodized. Aluminium is the most widely used metal in anodizing because of its natural properties. Few other metals that can be used in anodizing are as follows.AluminiumTitaniumMagnesiumTitaniumZincTantalumNiobium

5. Aluminium As above mentioned, aluminium is the most widely used metal for anodizing because of the properties it holds. There is more than one way to anodize aluminium. Aluminium is widely used in industries because of its strength and less weight ratio.

6. TitaniumTitanium is the second major used metal for anodizing after aluminium. Titanium has major usage in medical stuffs. Anodized aluminium is commonly used in dental and orthopaedic implants. Titanium is more extensively used in art and costumes, jewellery, body piercing jewellery, wedding rings because titanium can be anodized in attractive colour. These colour depends on the thickness of the anodizing.

7. Zinc Zinc anodizing is more complicated than other anodizing. It is anodized in the electrolytic solution like ammonium phosphate, chromate and fluoride combined with voltage as much as 200V DC. This adds anodize thickness of 80μm on the surface of the metal which makes it stronger and corrosion resistant.

8. MagnesiumThe most common purpose for anodizing magnesium is as a paint primer, with thin films (as little as 5 μm) being sufficient for this use. Thicker anodic coatings (25 μm or more) can provide magnesium materials with improve corrosion resistance. These coatings must be sealed with oil, wax, or sodium silicate for optimum effectiveness.

9. NiobiumNiobium can be anodized using chemistries and processes similar to titanium anodizing. A range of colours can be achieved by varying the coating thickness, which is, again, dependent on anodizing voltage. Anodized niobium is a popular material for costume and body jewellery, commemorative coins, and other highly aesthetic products.

10. Tantalum Anodizing tantalum requires a similar process to those used for titanium and niobium. A wide array of attractive colours can be formed by altering the film thickness. Voltage required for anodizing tantalum typically ranges from 18-23 Angstroms per volt, depending on the chemical solution used and process temperature. Anodized tantalum is most often used in the manufacture of capacitors.
