Uses of Electroplating
Uses of Electroplating
Practical Applications / Need:
Electroplating is a very useful process. It is widely used in industry for coating metal objects with a thin layer of different metals.
We list below some practical applications for which objects/articles are electroplated :
1. To Improve/alter Their Appearance:
We all have seen the shining handles of bicycles and bath taps which are otherwise made of iron. This is done by electroplating them with chromium or nickel. Similarly, articles of base metals are often coated with precious metals to make them look more attractive.
2. To Provide a Protective / Strengthening Coating:
We often find a chromium plating on bath taps, car bumpers, bicycle handles, towel rails, kitchen gas burners, wheel rims and so on. The chromium deposit not only provides a shiny appearance but also helps to avoid corrosion and scratches.
3. To Minimize the Cost:
We know that some of the metals like gold, silver, platinum, nickel and chromium are very expensive. But artificial jewellery is often made by electroplating gold or silver on less expensive metals.
4. Aesthetic Value :
Electroplating is used for coating a thin layer of expensive metals like gold, silver on the cheap metals to give attractive look to the final product.
5. Reduce Friction:
It is used in the area where we can reduce friction by coating certain kind of metal over the other.
6. Protection from Radiation :
It helps to protect from radaiton, abrasion and many other natural phenomenon just by imparting different metal layer on the surface.
