Abstract

The objective of this paper is to study the influence of H2S/CO2 partial pressure ratios on the corrosion behavior of carbon steel X60. In this work, micromorphology of corrosion product was investigated by X-ray diffraction and scanning electron microscopy. The corrosion behavior of X60 steel under different conditions was analyzed. The results showed that the presence of H2S induced the formation of iron sulfide films that provide protective properties to the metal and the corrosion rate decreased with increasing the H2S/CO2 partial pressure ratios. This behaver is because of the increase in the corrosion film thickness with increasing the H2S/CO2 partial pressure ratios.
