Summary: In this study, experimental and theoretical methods were used to explore the corrosion inhibition properties of banana leaves water extract (BLWE) for X70 steel in hydrochloric acid solution. It was found that BLWE can effectively inhibit both the anodic and cathodic reactions of X70 steel, leading to a high corrosion inhibition efficiency of approximately 90%. Analysis shows that the compounds in BLWE, such as AHP, ATI, and DDA, demonstrate excellent anticorrosion characteristics by forming a dense barrier film on the steel surface.

Summary: This study introduced the environmentally benign ingredient DEAE into the FFA formulation based on unsaturated diamine, showing excellent corrosion inhibition effect in acidic environment. The results indicated that DEAE facilitated the adsorption of NOPDA onto carbon steel surface, with adsorption mechanisms involving chemisorption, electrostatic attraction, and hydrogen bonding. The protective film formed on the surface of carbon steel was found to prevent the transfer of charge, providing a good reference for the application of unsaturated fatty diamine.

Summary: A comprehensive study was conducted to investigate the adsorption, corrosion inhibition efficiency and stability of acriflavine (ACF) on mild steel (MS) in 1 M HCl solution. The results showed that ACF adsorbs on the MS surface through chemical and physical interactions, forming a protective film that is uniform, adherent, and electrochemically stable. The inhibitor film exhibited high inhibition efficiencies of 92.8% and 97.1% after 1 h and 6 h immersion times, respectively. ACF was found to mitigate both anodic metal dissolution and cathodic hydrogen evolution reactions, making it an effective corrosion inhibitor for mild steel in acidic environments.

Summary: The corrosion resilience of annealed and quenched 434 ferritic stainless steel (434FS) was studied in the presence of 1 M H2SO4 with different NaCl concentrations. The results showed that annealed 434FS had the highest corrosion rate output, while untreated and quenched 434FS had lower corrosion resistance. The increase in NaCl concentration significantly affected the corrosion behavior of untreated and heat-treated 434 steels. Annealed 434FS exhibited the best passivation performance and resistance to localized deterioration.

Summary: This study evaluated the corrosion resistance of high carbon steel (HCS) in CH3COOH and C6H8O7 solutions with the addition of admixed citronella and myrrh essential oil extract (CNM). The results showed that CNM effectively inhibited corrosion in CH3COOH but performed poorly in C6H8O7 solution. Open circuit potential measurements indicated that CNM reduced the activation barrier for HCS corrosion. X-ray diffractometry and ATF-FTIR spectroscopy showed significant changes in the diffraction peaks and transmittance of certain compounds on the HCS surface in the presence of CNM.

Summary: This study investigated the corrosion protection efficiency of Citrus reticulate (CR) and Pelargonium (PG) oil distillates, as well as their combined admixture (CRPG), on mild steel in sulfuric acid (H2SO4) and hydrochloric acid (HCl) solutions. The results showed that CR and PG performed well in HCl solution at all concentrations, with optimal protection values of 85.94% and 89.68% at 1% and 1.5% distillate concentrations. However, their performance in H2SO4 solution was significantly dependent on concentration, with poor protection values at certain concentrations. The CRPG mixture exhibited effective protection in H2SO4 solution, while performing poorly in HCl solution. Statistical analysis revealed that inhibitor concentration had a significant impact on the protection performance, while exposure time had a marginal effect. The data also indicated that CRPG and CR had stable inhibition properties over time and concentration. Furthermore, the protection efficiency of CR and PG in both HCl and H2SO4 solutions exceeded the threshold value in a certain range of error, indicating their effectiveness in corrosion protection.
