discuss three uses of electroplating
Answers
1. Decorative purposes:
The electroplating improves the overall appearance of the metal. The common metals used are chromium, zinc, copper, nickel etc.
For example,
It is used in making inexpensive jewellery in which gold or silver plating is applied over inexpensive metal making it look more radiant and alluring.
Chromium plating is done on utensils and kitchen wares for shiny and pleasant appearance.
2. Protection against atmospheric conditions:
It is primarily used for protection against corrosion. A thin layer of metal which is more resistant to corrosion is applied over the metal. In this way, a protective layer is formed on the metal surface, making it less likely to be eroded.
For example, iron object is protected from corrosion by coating it with less reactive metals such as zinc, magnesium aluminium.etc.
3. Electrical conductivity:
Electrical conductivity can be increased by applying thin layer of metals which has conducting properties. For example, copper plating is used in communicating equipment and circuits.
4. Industrial applications:
Electroplating has various industrial uses not only for corrosion protection but also to improve many features. Some of the examples are
Automobile parts are plated with chromium to give them fine finishing.
Nickel plating is done on electrical connectors to improve friction.
Metals such as gold, zinc- nickel can withstand high temperature; therefore, engine parts are coated with these metals or alloys to reduce the damage caused by overheating.
For magnetic properties, nickel is coated on hard-drives which make them easier to read.
Electroplating is used to improve premature tarnishing of metals.
It makes brittle substances more durable and stronger.
Nickel plating with absorption properties make wide use in aviation, and aerospace.
Palladium plating is used to increase the thickness of the surface.
Answer:
Electroplating has wide range of uses. Apart from enhancing the metals appearance and protecting it from corrosion, there are many industrial application of electroplating.
