- 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.
4There 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

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.
6Titanium Titanium 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.

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.

- 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.
