Studies of Microbiologically Influenced Corrosion Using a Coupled Multielectrode Array Sensor

摘要

A newly developed multielectrode array sensor (MASS) was used to conduct a series of abiotic and bioticrntests to determine if the probe can detect corrosion induced by microbial activity. The probe was able torndetermine the maximum corrosion rate in the presence of sulfate reducing bacteria (SRB) and showed that thisrnrate was at least a factor of 10 greater than in the absence of SRBs. In addition, the corrosion rates obtainedrnusing the probe were much higher than those determined using linear polarization resistance furtherrndemonstrating its inherent better sensitivity to localized corrosion.
