Corrosion is the process by which certain materials, metals and non-metals, deteriorate as a result of oxidation. Rusting is oxidation of iron in the presence of air and moisture.

What is the difference between corrosion and rusting with example?

Rusting and corrosion both are oxidation reactions. Corrosion occurs over a wide range of objects while rusting is limited as it occurs only on iron. We can say rusting is a type of corrosion or most common example of corrosion as rusting of iron objects is very commonly found.

Is corrosion caused by rust?

Corrosion is an electrochemical reaction that appears in several forms, such as chemical corrosion and atmospheric corrosion, the latter of which is the most common form. When acidic substances (including water) come in contact with metals, such as iron and/or steel, rust begins to form.
