Synergistic Effect of A Hybrid Corrosion Inhibitor Based on Nigella Sativa and Zinc Cations To Improve the Corrosion Resistance of Mild Steel

Although mild steel structures are widely used in various industries such as pipelines and storage tanks, they are sustainable to corrosive environments. corrosion inhibitors can be used to enhance the anti-corrosion properties of the steel. the combination of two organic/inorganic inhibitors leads to a synergistic effect and improves the inhibitor performance in mild steel protection. in this study, the hybrid corrosion inhibitor based on nigella sativa and zinc cations was employed to improve the anti-corrosion properties of the mild steel. the inhibitive film fabricated on the mild steel in the presence of corrosion inhibitors was characterized using the scanning electron microscopy tests equipped with energy dispersive spectroscopy, fourier-transform infrared spectroscopy, raman spectroscopy, contact angle, x-ray diffraction pattern, and uv-vis tests. also, the electrochemical impedance spectroscopy and polarization tests were engaged in 3.5 wt. % nacl solution to study the protection performance of the mild steel in the presence of an inhibitory system. due to the fabrication of inhibitive film, the anti-corrosion properties of the mild steel are significantly enhanced in the presence of organic/inorganic corrosion inhibitors. the creation of the inhibitive film in the presence of hybrid corrosion inhibitors was proved through sem analysis and electrochemical testing. the calculated inhibition efficiency of 95% was calculated for hybrid corrosion inhibitor.
