Summary: The inhibitory performance and mechanism of compound nitrite with D-sodium gluconate on carbon steel in simulated concrete pore solution were studied. The results showed effective hindrance of pitting corrosion by the corrosion inhibitor, enhanced stability of the passive film on carbon steel, and competition with chloride ions for adsorption, weakening the adsorption of chloride ions on the steel surface.

Summary: Here, the synergistic inhibition effect of benzotriazole (BTA) and sodium D-gluconate (SD) on the corrosion of Q235 steel in simulated concrete pore solution (SCP) was systematically studied. The results showed that the mixed BTA/SD exhibited excellent anti-corrosion performance with an inhibition efficiency of 98.33%, higher than that of BTA (88.65%) and SD (92.16%). Surface analysis technologies confirmed the adsorption of BTA/SD on steel, and microscopy images demonstrated the protective effect of BTA/SD on steel in corrosive environment. The adsorption model and molecular dynamics simulation revealed the effective adsorption and anti-corrosion mechanism of BTA/SD. This study provides experimental and theoretical references for using synergistic inhibitors in corrosion protection of reinforced concrete structures.

Summary: Dendritic polymers with an isothiourea terminal group, carboxyl lateral group, and pentitol core dendrimers (ITCP-0G and ITCP-1G) were developed as novel phosphorus-free corrosion inhibitors for carbon steel in soft water. The corrosion inhibition performance of ITCP-1G was found to be superior to that of ITCP-0G, forming a stronger protective film on the steel surface. Larger dendrimer molecules provided better surface coverage and corrosion inhibition performance.

Summary: The corrosion behavior of 310S stainless steel was investigated in synthetic tap water and Ca2+ and Mg2+-free solutions with different concentration ratios. The specimens showed spontaneous passivation state and the pitting tendency increased with increasing concentration ratio of tap water. The carbonate scales deposited from the synthetic tap water solutions were mainly composed of CaCO3, which slightly affected the corrosion characteristics of the stainless steel.

Summary: This study explores the use of Vang tea leaves-water extract as a corrosion inhibitor for carbon steel in acidic solutions. The electrochemical data demonstrates that VTLWE acts as a mixed-type inhibitor, with its effectiveness depending on concentration. The results also indicate that VTLWE is more effective in inhibiting corrosion in 0.5 M H2SO4 solution than in 1.0 M HCl solution. Surface analysis further confirms the formation of an organic film layer on the steel surface.

Summary: In this study, the inhibition performance of different benzimidazole compounds on under-deposit corrosion of carbon steel in CO2-saturated solutions beneath CaCO3 and SiO2 deposits was compared. It was found that 2-SH-BI had the highest inhibition efficiency, and the effectiveness of different inhibitors varied under different deposits.

Summary: The study found that a liquid film with a thickness greater than or equal to 1 mm has no effect on the mechanism of the corrosion process, but has a control effect on the corrosion rate and the time of each stage in corrosion. The corrosion process can be divided into two stages: in the early stage, the concentration of ions inside and outside ADP is the same, so the corrosion is uniform; in the later stage, due to the influence of CO2 dissolution and mass transfer distance, the cathodic reaction is mainly outside ADP and the anodic reaction is mainly inside ADP. In addition, corrosion acidification occurs in ADP, which enhances the corrosion process in ADP.

Summary: Carbon steel is widely used in various industries, and its corrosion is a major concern. Carbon dots (CDs), especially heteroatom-doped CDs, have been developed as green corrosion inhibitors. A study compared the corrosion inhibition efficiency and mechanisms of nitrogen-doped and nitrogen, sulfur codoped CDs. The results showed that both types of CDs can effectively restrain the corrosion of carbon steel, with the codoped CDs exhibiting higher inhibition performance. Molecular dynamics simulation revealed the strong interaction between the codoped CDs and the carbon steel substrate, which contributes to the superior corrosion inhibition.

Summary: Ethylene diamine-N,N'-disuccinate (EDDS) is successfully intercalated into layered double hydroxide (LDH) sheets, resulting in the hybrid assembly [Zn2Al(OH)6]+ [EDDS]4-0.25 2H2O (LDH-EDDS4-). The presence of functionalized LDH-EDDS4- significantly decreases the surface reactivity of carbon steel in a neutral and aerated sodium chloride solution. The synergy effect between Zn2+ cations and EDDS4- anions is highlighted, and SEM and visual observations confirm the efficiency of hybrid LDH-EDDS4- in protecting the carbon steel surface from corrosion.
