From Wikipedia, the free encyclopedia. Microbial corrosion, also called bacterial corrosion, bio-corrosion, microbiologically influenced corrosion, or microbially induced corrosion (MIC), is corrosion caused or promoted by microorganisms, usually chemoautotrophs.It can apply to both metals and non-metallic materials.acterial corrosion may appear in form of pitting corrosion, for example in pipelines of the oil and gas industry. Anaerobic corrosion is evident as layers of metal sulfides and hydrogen sulfide smell.
Metals that are dissimilar to one another, vary with regard to their differences in corrosion. Galvanic corrosion is a process that indicates a comparison of how metals corrode differently when in contact with an electrical connection.This system of ranking dissimilar metals is called the Galvanic Series which gives a good suggestion of which metals will be more likely to corrode first.alvanic Corrosion. According to the Multimedia Corrosion Guide, the definition of Galvanic Corrosion is âthe effect resulting from contact between two different metals or alloys in a conducting corrosive environmentâ.
