Correct Answer - Option 1 : Electro-polishing
Electrolysis:
Electrolysis is a chemical process in which the direct electric current (I) is passed through an electrolyte containing ionic compounds, which can be in either the molten state or aqueous phase. Following is the process which is done by the electrolysis.
Electrodeposition:
It is the process by which one metal is deposited over another metal or non-metal by electrolysis.
The applications of Electrodeposition is as follows:
Electro facing:
It is the process of coating a metallic surface with a harder metal by electrodeposition.
Electroplating:
Electroplating is defined as the deposition of metal over any metallic or non-metallic surfaces. Electroplating is usually employed
1. To protect the metals from corrosion by atmospheric air, moisture, and CO2.
2. To give the reflecting properties to reflectors.
3. To replace worn-out metals.
4. To give a shiny appearance to articles.
Electropolishing is a reverse process of electroplating.
Electro-forming:
Electrotyping (Electro-forming) is a chemical method for forming metal parts that exactly reproduce a model. It is also done by electrolysis.
