Prevention
In the case of metallic
objects corrosion may be defined as an electrochemical process
which affects in most cases the aesthetics and longevity of an
object. The mechanism is based on anode and cathode reactions
in an electrolyte. Corrosion takes place at the anode with the
release of hydrogen gas or the formation of hydroxyl ions at
the cathode. These hydroxyl ions may react with metal ions dissolved
at the anode and form metal hydroxides or hydrated oxides. If
these are insoluble they will deposit as a passive layer on the
metal surface and may reduce the rate of corrosion as in the
case of stainless steels. |
The main technique available for reducing corrosion is to eliminate
the electrolyte, either by:
-
Drying out the environment; e.g. reducing
the humidity to below 35% can virtually eliminate corrosion
of mild steel.
-
Providing a barrier between the metal and the electrolyte
by passivating or providing a protective anti-corrosion coating.
