... First, the corrosion product film was immersed in oilfield injection water and the effect on the corrosion behavior and the corrosion reaction mechanism were constantly observed during this period. The effect was displayed by potentiodynamic polarization curve and electrochemical impedance spectrums...

... polarization curves data were taken into account. Hydrodynamic effects were analyzed by Rct and corrosion rate data. Design/methodology/approach Electrochemical impedance spectroscopy and potentiodynamic polarization techniques were used to assess the electrochemical behavior for five pipe steels steel...

... was recorded for all steels exposed to soil at different exposure times. Thus, the electrochemical impedance spectroscopy (EIS) was traced, and anodic polarization curves were obtained. Findings The steel corrosion processes started when the active sites were exposed to natural acidic soil. However...
