Summary: This study investigated the tidal corrosion of X80 pipeline steel in an inoculated marine tidal environment using weight loss, SEM/EDS, and electrochemical measurements. The results showed that D. desulfuricans accelerated the corrosion process, and the acceleration effect increased with the altitude of the specimen in tidal zones.

Summary: Green corrosion inhibitors, such as Citrus limetta peel extract, have gained attention for their cost-effectiveness, biodegradability, and eco-friendly characteristics in inhibiting the corrosion of metallic alloys. This study investigates the corrosion inhibition efficiency of Citrus limetta peel extract on mild steel surfaces in an acidic environment using electrochemical methods. The results demonstrate that the extract exhibits a corrosion inhibition efficiency of 93% on mild steel surfaces in hydrochloric acid media. The adsorption mechanism of the peel extract on mild steel surfaces involves both physisorption and chemisorption.

Summary: The Open Circuit Potential (OCP) technique is a non-destructive method used to survey and monitor corrosion in reinforced concrete structures. By adopting combined wetting/drying cycles and partial immersion of specimens in NaCl solution, earlier appearance of corrosion can be achieved, shortening the testing period. Incorporating 30% SBAS and 3% WTPS can provide higher protection for steel corrosion, showcasing the wide applicability of the OCP technique to various cementitious matrices.

Summary: The corrosion behaviors of low-alloy steel were studied in simulated tidal zones using various testing methods. The results showed that the corrosion in tidal zones was more severe than in the immersion zone, with the low tide and middle tide zones experiencing more severe corrosion than the high tide zone.

Summary: A thick cementite skeleton exposed on a ferritic-pearlitic C1018 steel surface significantly reduced inhibition efficiency after pre-corrosion, while this effect was insignificant for a lower carbon X65 steel with dispersed cementite microstructure, as only a small amount of cementite remained on its surface after pre-corrosion. Normalizing the increased cathodic area in the presence of residual cementite back to the original area inhibited both anodic and cathodic reactions to the same extent as on bare steel with a sufficient inhibitor concentration. However, the detrimental effect of cementite cannot be completely eliminated due to its galvanic coupling effect.

Summary: This study evaluates the corrosion inhibition efficiency of thioridazine hydrochloride (TH), an antipsychotic drug, on mild steel in 1 M hydrochloric acid. The results show that TH significantly enhances the polarization resistance and reduces the corrosion current density of mild steel. Long-term exposure tests demonstrate that TH has a highly effective corrosion inhibition effect on mild steel.

Summary: Garlic peel, as a green inhibitor, demonstrated efficient corrosion inhibition capabilities in different aqueous solutions, especially in alkaline conditions. Mass loss and electrochemical corrosion tests confirmed the efficiency of garlic peel in acidic, neutral, and basic solutions. SEM/EDS analysis revealed the reduction and alteration of corrosion products, while quantum simulation explained the superior performance of garlic peel in NaOH solution, attributing it to the generation of more active species.

Summary: This study presents a new method for directly fabricating a superhydrophobic surface coating on mild steel. Dielectric barrier discharge (DBD) plasma was used to convert a liquid small-molecule precursor to a solid film through plasma-assisted on-surface polymerization. The properties of the coating were analyzed using various techniques, including microscopy, spectroscopy, and contact angle measurement. The results showed that the wettability of the films could be controlled by adjusting the plasma parameters and incorporating graphene nanoplatelets in the precursor. High-dose plasma exposures of the nanoplatelet-containing precursor resulted in the formation of superhydrophobic films with water contact angles above 150 degrees. However, the superhydrophobic coating provided limited corrosion protection according to potentiodynamic polarisation tests.

Summary: In-service monitoring of buried corrugated metal pipes and culverts is crucial to prevent sudden failure due to prolonged corrosion. This paper proposes an accelerated laboratory corrosion test to simulate the effects of chloride deposits on buried corrugated mild steel structures. The test shows that increasing the number of wet/dry cycles accelerates the corrosion and deterioration in steel strength, ductility, and hardness. The paper also presents a mathematical model for predicting corrosion damage based on physicochemical indicators.
