Atmospheric corrosion studies in a decommissioned nuclear power plant

Metallic corrosion progresses at a very low rate at room temperature in a perfectly dry atmosphere and for practical purposes may be ignored, but on humid surfaces is a very relevant phenomenon. The mechanism is electrochemical, with an electrolyte constituted by an extremely thin moisture film of j...

description Metallic corrosion progresses at a very low rate at room temperature in a perfectly dry atmosphere and for practical purposes may be ignored, but on humid surfaces is a very relevant phenomenon. The mechanism is electrochemical, with an electrolyte constituted by an extremely thin moisture film of just a few monolayers or an aqueous film of hundreds of microns in thickness due, for instance, to rain or dew (Rozenfeld, 1972; Barton, 1976; Feliu and Morcillo, 1982; Kucera & Mattson, 1986; Costa et al., 2006).
