摘要: Microbiologically influenced corrosion inhibition (MICI) has been observed for Al 2024, mild steel and cartridge brass when an artificial seawater (AS) solution containing growth medium was contaminated by bacteria. Impedance data clearly showed that pitting did not occur under these circumstances 2024. For rates were decreased significantly. also greatly tarnishing observed. Analysis of electrochemical noise obtained the three materials in AS with without reveal significant changes due to MICI except increase resistance Rn a parallel shift current power spectral density plots lower values 2024 steel. The mainly decrease standard deviation fluctuations.
