Effect of temperature on CO2 corrosion of carbon steel

Abstract

This work investigates the effect of temperature on the corrosion product layer of carbon steel exposed to a CO2-containing solution. The measurement techniques, such as scanning electron microscopy with energy dispersive spectrometry, X-ray diffraction, and X-ray photoelectron spectroscopy, were used to systematically characterize the morphology and composition of the corrosion product layer. The corrosion rates were calculated by weight loss method. The corrosion mechanisms as a function of temperature are studied and discussed. The results showed that temperature is an important factor in the corrosion rate of carbon steel. © 2009 John Wiley & Sons, Ltd.
