- The
impact of corrosion is felt in three areas of concern—economics,
safety, and environmental damage
-
Materials subject to corrosion include engineering materials,
such as metals, plastics, rubber, and ionic and covalent solids;
aggregates such as concrete, composite materials; and wood.
- The
eight forms of corrosion defined by Fontana are general
corrosion, pitting corrosion, intergranular corrosion, parting,
galvanic corrosion,
crevice corrosion, stress-corrosion cracking , and erosion
corrosion
- Pure
metals and their alloys interact gradually with the elements of
a corrosive medium to form stable compounds and the resulting
metal surface is considered to be ‘corroded’.
- Acid
cleaners are primarily used to remove inorganic deposits
such as lime scale, rust, etc. Acid cleaning agents are also
used to pickle stainless steel. The type of acid chosen to clean
the metal depends on the substrate and the type of contamination
- The
detrimental side-reaction between an acid and metal can be
greatly reduced by the addition of inhibitors to the acid
solution. Inhibitors are often comprised of organic nitrogen
and/or sulphur compounds togetherwith surfactants. Surfactants
ensure that the surface is thoroughly wettened with the
solution, which in turn results in a more uniform surface
reaction and prevents localized corrosion
- The
inhibitor counters corrosion by forming a thin film on the
surface of the metal. The surface of the metal is slightly
charged, as a result of which polar organic compounds
(inhibitors) are drawn to the surface and form the
protectivelayer.
- Each
type of acid requires a specific inhibitor; moreover not all
inhibitors are capable of protecting every type of metal. For
this reason it is important to use the appropriate inhibitor for
the specific acid.
