what is corrosion ? and how can we prevent it
Answers
Answer:
When some metals are exposed to moisture, acids etc., they tarnish due to the formation of respective metal oxide on their surface. This process is called corrosion. Corrosion can be prevented by painting the surface, oiling, greasing, galvanizing, chrome plating or making alloys.
Answer:
corrosion is a process which converts the refined metal into more chemically stable form.
There are 5 types of corrosions they are:
1. galvanic
2. stress cracking
3. General
4. localised
5. caustic agent
To prevent the metal from corrosion following steps are to be followed:
1. using a corrosion resistant metalsuch as aluminium
2. the metal should be painted with yellow colour paint to prevent the corrosion.
3. design modifications- By modifying the design corrosion will be prevented.
4. corrosion inhibitors should be used.
5. environmental measures should be taken such as the metal should not be kept in a humid area.
