Inhibition of Microbiologically Influenced Corrosion.

Abstract

Two areas of work designed to provide a better understanding on the nature of microbial colonization of surfaces and microbiologically influenced corrosion are discussed. The first approach examined a mechanical sensing model to describe microbial colonization. Results obtained alter the exposure of a group polydimethylsiloxane polymers to an estuary environment provide support for this model. The second approach sought to determine it there is a relationship between microbial colonization' of certain metallic substrates and corrosion. Exposure of zirconium, chromium, niobium, tantalum. molybdenum. tungsten and 4340 steel to Postgate medium with 2.5% NaCI and sultate reducing bacteria (SRB) resulted in biofilms being formed on all samples. In the case of the zirconium, chromium, niobium, and tantalum samples. the weight loss after two years of exposure was negligible.
