METHODS FOR INHIBITING MICROBIOLOGICALLY INFLUENCED CORROSION OF METALS AND ALLOYS

摘要

Methods for inhibiting the microbiologically influenced corrosion of a metal are provided comprising treating the surface of the metal with a microbiologically influenced corrosion inhibiting effective amount of a source of rare earth metal ions; wherein the surface of the metal is in the presence of corrosive reagents such as chloride ions and acids and one or more microorganisms capable of colonizing on and/or embedding into the surface and preventing self-healing of the surface of the metal damaged by the corrosive reagents.
