Description:

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. – PowerPoint PPT presentation

  • 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.

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.AluminiumTitaniumMagnesiumTitaniumZi

  • 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
Titanium 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.
