A multi-disciplinary, multi-industry overview of
microbiologically influenced corrosion, with strategies for
diagnosis and control or prevention
Microbiologically Influenced Corrosion helps engineers
and scientists understand and combat the costly failures that occur
due to microbiologically influenced corrosion (MIC). This book
combines recent findings from diverse disciplines into one
comprehensive reference. Complete with case histories from a
variety of environments, it covers:
* Biofilm formation
* Causative organisms, relating bacteria and fungi to corrosion
mechanisms for groups of metals
* Diagnosing and monitoring MIC
* Electrochemical techniques, with an overview of methods for
detection of MIC
* The impact of alloying elements, including antimicrobial
metals, and design features on MIC
* MIC of non-metallics
* Strategies for control or prevention of MIC, including
engineering, chemical, and biological approaches
This is a valuable, all-inclusive reference for corrosion
scientists, engineers, and researchers, as well as designers,
managers, and operators.
