Corrosion is a serious problem. Every year an enormous amount of money is spend to replace damaged iron. What steps can be taken to prevent this damage? What will learners infer from this information?
The rusting of iron can be prevented by painting, oiling, greasing, galvanising, chrome-plating, anodising or making alloys. The learner will be able to know how to escape from the economic loss of metallic objects by keeping them corrosion resistant.
