Identify the process represented by the following diagram. Describe the process in short. ltbgt

Explanation

The diagram represents galvanizing process.
i. Galvanizing is a process of giving a thin coating of zinc on iron or steel materials to protect them from corrosion.
ii. In this method, corrosive metal like iron (or steel) is dipped in molten zinc. Thus, a thin layer of zinc gets coated on the metal surface.
iii. Zinc, being more electropositive than iron, undergoes corrosion first. Thus, it prevents corrosion of iron.
iv. However, if zinc layer goes away and the inner iron gets exposed, then the inner iron layer will start to rust.
