Microbiologically Influenced Corrosion: Global Phenomena, Local Mechanisms

摘要

Much of the on-going research in microbiologically influenced corrosion (MIC) is directed al identification of unifying mechanisms for global observations of MIC-related phenomena, e.g. ennoblement of passive alloys and corrosion of carbon steel pilings. Both occur in fresh and saline waters In the following sections data will be presented suggesting that a single explanation for either is unsatisfactory. The two examples provide evidence that MR mechanisms can he site specific and multiple mechanisms can be operative, especially in coastal waters where water chemistry varies with location and is subject to riverine inputs and tidal fluxes.
