Question

How Can Corrosion Be Prevented?

Answer 1

Corrosion- When the surface of any metal is destructed due to atmospheric conditions. There are a few techniques by which corrosion of metal surfaces is prevented.

Prevention of corrosion are

1. Electroplating- It is a process in which a metal is coated with another metal's thin layer by electrolysis.
2. Cathodic Protection- In this technique, two types of metals are used, one is base metal while another is sacrificial metal. The base metal is connected with sacrificial metal in such a manner, corrosion takes place in sacrificial metal and the base metal is protected. This happens because sacrificial metal is more reactive, it will lose electrons easily as compared to the base metal. Thus base metal is protected.
3. Galvanization- It is a process which includes zinc and iron. It involves the dipping of iron into molten zinc. Due to this process, iron is protected from being corroded.
4. Painting and Greasing- When the surface of any metal is painted or greased, it has no effect on the atmospheric condition on them. Thus, they prevent corrosion.
5. Using Corrosion Inhibitor- It is a chemical which is added to the metal to lower the effect of corrosion.
6. Make use of the Right Material- There are many materials which resistant to corrosion like aluminium.

So, These are methods by which corrosion of metal surface can be controlled.
