CORROSION- In case of metals and articles made of metals, it has been found that certain gases present in the atmosphere and moisture attack on the surface of metal and destroy it , forming compound and expose it for further action.
METHODS TO CONTROL CORROSION- there are the following methods to control corrosion.
1. METAL SPRAYING - this id the modern method of developing a protective coating. The molten netao is sprayed over the surface by a spraying gun.
2. HOT DIPPING- This methods of developing a protective metallic coat over the surface is chiefly utilised in those metals whose melting point has low values e.g. zinc, tin and lead etc.
3. ELECTROPLATING - The modern method of developing the metallic coat. Here the coating is done by electrical process. An electrolyte solution of the costing metal is electrolysed using the base metal as a electrode.
4. GALVANIZATION - In this method, we apply coating of zinc over iron articles. A uniform coating of zinc is formed over iron since zinc is much more reactive than iron, so it protect iron from corrosion.
5. TINNING - we apply a coating of tin over iron, this method is known as tinning.
