Inhibiting Performance of Rivaroxaban Against Corrosion of Mild Steel in 1.0 M HCl Solution

Before being used in a variety of sectors, steel is often cleaned using acidic solutions. The steel corrosion rises because of this treatment, necessitating the inclusion of inhibitors in the cleaning bath. Due to this, it is constantly crucial to provide new and effective corrosion inhibitors. Rivaroxaban was investigated in this study as a mild steel corrosion inhibitor in a 1.0 M HCl solution. Corrosion experiments were conducted using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The considered temperatures were 25 degrees C, 30 degrees C, 40 degrees C, and 50 degrees C, and concentrations of the inhibitor were 1, 10, 20, 30, and 40 mu M. Steel sheets' surfaces were analyzed using SEM images in both the absence and presence of the inhibitor. At an ideal concentration of 40 mu M, Rivaroxaban demonstrated inhibition efficiency greater than 92%, which was reduced with an increase in temperature and time of immersion in the acidic solution. Charge transfer resistance in the presence of Rivaroxaban after 144 h decreased from 1470 to 231 omega cm2.
