Electroplating is done to:
1. Protect metals against corrosion:
- One of the main reasons for electroplating is to protect metals from corrosion.
- Corrosion is the process of gradual deterioration and damage to metals due to chemical reactions with the environment.
- By electroplating a metal with a protective layer of another metal, the base metal is shielded from direct contact with corrosive substances such as air and water.
- The electroplated layer acts as a barrier, preventing the base metal from oxidizing and corroding.
2. Give a shiny appearance to articles:
- Electroplating is commonly used to enhance the aesthetic appeal of various objects.
- By electroplating a metal with a layer of a more visually appealing metal, the object's surface can be made shiny and reflective.
- For example, objects like jewelry, silverware, and decorative items are often electroplated with precious metals like gold or silver to give them an attractive and lustrous appearance.
3. Repair worn-out materials:
- Electroplating can also be used to repair worn-out materials.
- In some cases, the surface of an object may become worn, damaged, or corroded over time.
- Electroplating can be employed to restore the surface of the object by applying a fresh layer of metal.
- This process can help to fill in any gaps, cracks, or imperfections in the surface, improving the overall appearance and functionality of the object.
4. All of these:
- Electroplating serves multiple purposes, including protection against corrosion, enhancing appearance, and repairing worn-out materials.
- These purposes are not mutually exclusive, and electroplating can be used for all of these reasons simultaneously.
- By combining the benefits of corrosion protection, aesthetic improvement, and material restoration, electroplating offers a versatile solution for a wide range of applications.
