We need to what type of conditions are required for rusting to occur and then suggest as many ways possible of preventing it.
Learning Intention
After doing this learning bite you will:
Know how rusting occurs and how it adversely affects the properties of iron.
Learn about and remember that the 3 main ways of corrosion protection are surface protection, alloying and electrochemical protection.
