Özet

© 2022 Elsevier B.V.In this study we evaluated the corrosion inhibition potential of an environmentally friendly, cost effective and beneficial compound on carbon steel in an acidic environment. We investigated electrochemical as well as gravimetric measurements for corrosion performance inhibition of the acetylsalicylic acid ASA molecules used from carbon steel XC48 in HCl 1M solution. The results show that aspirin inhibits the corrosion of carbon steel in acidic environment. It was found that the inhibition efficiency of aspirin increased with increasing inhibitor concentration and decreased with increasing temperature. The maximum inhibition efficiency was 96% with 5×10−3 M aspirin at 308 K. The inhibition efficiency increased with increasing concentration of ASA. This inhibitor adsorbs on the metal surface according to the Langmuir model and a physical adsorption mechanism is proposed for the adsorption of the inhibitor on the carbon steel surface, the scanning electron microscopy (SEM), the Thermodynamic and the kinetic parameters were calculated and discussed.
