Microbiologically Influenced Corrosion
This chapter focuses on the effects of microscopic organisms and the by-products they produce on the electrochemical corrosion of metals. It begins by considering the characteristics of organisms that allow them to interact with the corrosion processes, the mechanisms by which organisms can influence the occurrence or rate of corrosion, and the types of corrosion most often influenced by microbes. The chapter then discusses the formation of biofilms on the surface of metals. This is followed by a list of industries most often reported as being affected by microbiological corrosion, along with the organisms usually implicated in the attack. The types of attack that have most commonly been documented are illustrated through generalized case histories for different classes of alloys. The chapter also describes the general approaches to be taken to prevent microbiologically influenced corrosion. It ends with some information on the inhibition of corrosion by the action of bacteria.
