Microbiologically Influenced Corrosion (MIC) Accelerated Testing Using a Flow-Through System

摘要

Microbes recovered from sediments, slime, tubercles, or corrosion coupons were characterized into functional groups, identified by fatty acid patterns and used in a flow-through test system. Test solutions were prepared as field conditions and supplemented with nutrients for the growth of microbes. Four-sided working electrodes were fabricated to simplify experimental design by combining four steel disks from the same stock into one probe. Concentric electrodes were made to simulate localized corrosion and study the effect of bacteria upon stability of localized corrosion.
