3. INTRODUCTION
◦Metallic coating is a process that involves applying a
thin layer of metal to a surface in order to improve its
properties. This can be done through various methods
such as galvanization, tinning, and electroplating. While
this may seem like a small detail, it can have a
significant impact on the durability, corrosion
resistance, and aesthetic appeal of the material.
◦In today's world, metallic coating plays a crucial role in
various industries such as automotive, construction, and
electronics. The benefits of this process are numerous,
making it an essential aspect of modern manufacturing.
In this presentation, we will explore the different types
of metallic coating, their advantages and disadvantages,
and their applications in different industries.

4. GALVANIZATION
•Galvanization is a process of coating iron or steel with
zinc to protect it from corrosion. This is done by
dipping the metal into a bath of molten zinc, which
forms a protective layer on the surface of the metal.
•There are several benefits to galvanization, including
increased durability and resistance to rust and
corrosion. Additionally, galvanized metal has a shiny,
attractive appearance that makes it popular in
architectural and decorative applications.

5. TINNING
•Tinning is the process of coating a metal surface with a thin layer of
tin. This is usually done to prevent rust and corrosion, as well as to
improve the metal's appearance. The process involves cleaning the
metal surface, applying a flux to help the tin adhere, and then
heating the metal while applying the tin.
•Tinning has many applications in various industries. It is commonly
used in the food industry to line cans and other containers to
prevent contamination. It is also used in electronics to protect wires
and components from corrosion. Additionally, tinning can be used
to improve the solderability of certain metals.

6. ELECTROPLATING
Electroplating is the process of depositing a thin
layer of metal onto a conductive surface using an
electric current. This method is commonly used to
improve the appearance, corrosion resistance, and
wear resistance of objects.
During electroplating, the object to be plated is
submerged in a solution containing ions of the
metal to be deposited. An electrode made of the
same metal is also placed in the solution, and an
electrical current is passed through the system. The
metal ions in the solution are attracted to the
object's surface and form a thin, uniform layer on
top of it.

9. CONCLUSION
•In conclusion, metallic coating plays a crucial role in various
industries, including automotive, construction, and electronics. The
benefits of metallic coating are numerous, including corrosion
resistance, durability, and aesthetic appeal. By protecting against
rust and wear, metallic coating can extend the lifespan of products
and reduce maintenance costs. Additionally, the use of metallic
coating can enhance the appearance of products, making them more
visually appealing to consumers.
