    8. Corrosion and its treatment

    In very general terms, corrosion can be defined as the progressive destruction of building materials by their environment, making electrochemical corrosion of metals the primary source of the corrosion we'll be discussing in this section. There are, however, other sources of corrosion: mechanical erosion, erosion by moving solids, erosion under the influence of high-speed fluids (cavitation) and microbiological attack on materials.

    • Metal/electrolytic solution interface

      This interface is unique in that it combines an electron conductor, the metal, with an ionic conductor or electrolyte, the aqueous solution. At this interface, a few particles from each of the two phases can interact; for example, cations can capture electrons from the metal to form neutral species, the metal...
