Corrosion inhibition performance of imibenconazole for mild steel in sulfuric acid: A comprehensive investigation Onkarappa, Nayana Kudluru Satyanarayana, Jeevan Chakravarthy Arakalagudu Adarakatti, Prashanth Shivappa Mild steel Adsorption Sulfuric acid Imibenconazole Electrochemical analysis In this work, the efficacy of imibenconazole (IB) as a new mild steel corrosion inhibitor in 1 N sulfuric acid is examined. With 95.4-96.6% inhibition at an ideal dose of 500 µM, weight loss measurements show strong inhibitory efficiency. The formation of a protective coating by imibenconazole on the steel surface is demonstrated by scanning electron microscopy (SEM) photographs. Improvements in charge transfer resistance (Rct), a shift in Tafel lines to higher potentials, and a drop-in double-layer capacitance (Cdl) are indicative of improved corrosion resistance as measured by electrochemical methods. The inhibitor’s adsorption aligns with the Langmuir isotherm, and the values of ΔG°ads (25-30 kJ/mol) indicate a combined physisorption and chemisorption mode of adsorption. Reliable long-term corrosion prevention is ensured by its durable protective action up to 120 h. Due to its adaptability, the inhibitor can be applied by coatings, injections, and immersions, making it suitable for a range of situations. While stressing the need for more research to examine the applicability of imibenconazole in various materials and situations, the study offers a strong foundation for the adoption of imibenconazole as an efficient corrosion inhibitor. To guarantee long-term protection and effectiveness, routine maintenance and observation are recommended.
