An electrochemical and X-ray computed tomography investigation of the effect of temperature on CO2 corrosion of 1Cr carbon steel
Abstract
This paper presents the investigation on the effect of temperature on the corrosion behavior of 1Cr carbon steel at 40 °C and 80 °C in 1 wt. % NaCl aqueous solution saturated with CO<sub>2</sub>. The evolution of the corrosion process was followed with Linear Polarization Resistance (LPR) and Electrochemical Impedance Spectroscopy (EIS). X-ray Computed Tomography was used for 3D structure of the scale ex-situ to correlate with electrochemical investigation. Additionally, the surface morphology of the corrosion products was analyzed with Scanning Electron Microscopy (SEM) and structural information using X-ray powder diffraction (XRD). Tomography results showed protective FeCO<sub>3</sub> formation with three different layers at 80 °C, where corrosion underneath the scale was uniform. The 3D image of the corrosion products formed at 40 °C showed loose and porous, and consequently did not reduce the corrosion rate unlike for 80 °C. Low temperature test also showed signs of localized corrosion beneath the corrosion products.
