Simulated Microbial Corrosion in Oil, Gas and Non-Volcanic Geothermal Energy Installations: The Role of Biofilm on Pipeline Corrosion

“…The higher polarization resistances (R p ) and Tafel slopes (b a and b c ) in distilled water than in brine solution imply lower corrosion current densities (I corr ) in distilled water than in brine solution (Pan et al, 2017). Addition of biofilm on the coupon surfaces decreases the corrosion current densities for test coupons without simulated biofilm in distilled water experiments with 60 min exposure time by 0.04, 0.06 and 0.12 mA cm −2 at temperatures of 30, 45 and 60 • C, respectively.…”

Inconsistent evolvement of micro-structures and corrosion behaviors in cold/warm deformed austenitic stainless steel

“…Electrochemical behaviors of cold/warm deformed 304 SS samples were analyzed by potentiodynamic polarization tests, and the results are shown in figure 7. In the potentiodynamic polarization plots, several related parameters (corrosion potential: E cp , passivation current density: i pc , pitting potential: E pp , and length of the passive region: ΔE (ΔE=E pp -E cp )) were acquired by polarization plots and Tafel extrapolation method [21,22]. The i pc represented the current in the middle of the passive region of the polarization plot.…”
