摘要

The work investigated the influence of acetic acid (HAc) on the corrosion behavior of carbon steel exposed to the simulant solution. The analysis methods such as scanning electron microscopy, x-ray diffraction, energy dispersive spectroscopy, and x-ray photoelectron spectroscopy were employed to systematically characterize the morphology and component of the corrosion film. The corrosion rate was calculated by weight loss and electrochemical methods. In addition, the corrosion behavior was further studied by using potentiodynamic polarization and electrochemical impedance spectroscopy. It was shown that the corrosion potential and current density increased with increasing the amounts of HAc. The HAc concentration has an important effect on the corrosion film and the corrosion mechanism.
