EVALUATE PERFORMANCE AND ANALYSIS CORROSION PRODUCTS FOR CARBON STEEL IN ACIDIC MEDIA
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 3
Abstract
The performance of carbon steel (C1010) has been evaluated in three acidic solutions: 1M HCL,1M H2SO4, 1M CH3COOH after immersion for 30 minutes and 300 minutes.The corrosion rate was determined by linear polarization resistance and potentiondynamic polarization techniques, and the corrosion rate in a short time of immersion was slightly higher than in a longer period of immersion due to deposits of the corrosion product on the sample surface slowing down the cathodic reaction rate and metal dissolution (anodic reaction), which can be clearly seen in PDP curves. In addition, X-ray photoelectron spectra was used to provide information on the actual compound present on the sample surface. Fe 2p, O 1s, Cl 2p, S 2p, C 1s core level spectra demonstrate that substrate termination does vary according to acidic solution type, with chloridic, sulfate, and acetate films being exhibited on top of the surfaces of samples when immersed in 1M HCl, 1M CH3COOH, and 1M H2SO4 respectively. The information provided by XPS supports and complements the data obtained from other techniques as mentioned above. All results indicate that the corrosion resistance of carbon steel in acetic acid is higher than hydrochloric acid or sulfuric acid due to the higher rate of hydrogen evolution in the latter. In other words, the worsening of surface film stability in carbon steel occurs much faster in H2SO4 than HCl or CH3COOH.
