What is rusting?

"Rusting applies to the corrosion of iron or iron-based alloys with formation of corrosion products
consisting of hydrous ferric oxides. Nonferrous metals, therefore, corrode but do not rust."
- From Corrosion and Corrosion Control, third edition, H.H. Uhlig, and
R.W. Revie, John Wiley and Sons, 1985.
