Many times, you want to protect metals from corroding. A common process
that is used to protect metals is called electroplating. Electroplating,
is a process of dipping a piece of metal into a substance that you wish to
use as a protective coating, and then applying electricity to allow the
reaction to take place. Once the coating is placed on the metal, the
coating oxidizes and the metal stays unharmed. A common type of
electroplating that is used often is called galvanizing. Galvaniziing, is
a process that coats iron with zinc. (Look through the nails section the
next time that you are in the hardware store and you will probably find
that outside nails are galvanized.)
