Summary: In this study, we investigated the corrosion of galvanized steel in a high-humidity neutral atmosphere. The results showed that damaged galvanized steel exhibits good corrosion resistance at 50 degrees Celsius, but at 70 degrees Celsius and 90 degrees Celsius, the corrosion of the base metal is accelerated by the damage to the galvanized layer.

Summary: Accelerated methods are necessary to test organic coatings in less time, as testing under natural conditions is time-consuming. Investigating the correlation between accelerated and natural aging test results is important due to the inability of a simulated environment to fully reproduce actual operating conditions. This study examines the natural aging of painted steel, aluminum, and hot-dip galvanized steel under continental climate conditions for 1 year. The extent of deterioration is compared with samples weathered through accelerated testing, using various measurement techniques. The results highlight challenges in predicting the durability of organic coatings for metal structures.

Summary: This study evaluated the corrosion effect of stainless steel and galvanized steel exposed to emulsified diesel, diesel, and biodiesel. The results showed that stainless steel had a lower corrosion rate in emulsified diesel compared to biodiesel, while galvanized steel had a higher corrosion rate in emulsified diesel than biodiesel. The higher acidity of emulsified diesel due to additives was suggested as a possible cause for the increased corrosion. However, the corrosion level of stainless steel in emulsified diesel was found to be within an acceptable range.

Summary: The Scanning Kelvin Probe was used to study passivation of AISI 304L stainless steel after cathodic polarisation, revealing the enrichment of surface film by Fe (II) hydroxides due to hydrogen effusion from the bulk. Pre-polarisation was found to accelerate crevice corrosion in the presence of chlorides. SKP mapping showed increased hydrogen sub-surface concentration and decreased passivity in the anodic zones of the crevice.

Summary: Due to the porous nature of the coatings produced through the plasma electrolytic oxidation (PEO) process, sol-gel coatings have been widely studied as a post-treatment to enhance the protective characteristics. This study investigated the sealing ability and corrosion resistance properties of four types of PEO/sol-gel coating systems on AA2024 alloy using different sol-gel precursors. The performances of the coatings were evaluated through electrochemical impedance spectroscopy (EIS) and Scanning Vibrating Electrode Technique (SVET) analysis. The results showed that the sealing ability and corrosion resistance of the duplex PEO/sol-gel coating were greatly influenced by the sol-gel precursors and their network properties.

The corrosion protection performance of the encapsulated Zn.MBO in NCHS (Zn.MBO@NCHS) was evaluated on bare and epoxy-coated AA2024. The release of MBO and zinc cation from the capsules was analyzed at different pH levels. The electrochemical impedance spectroscopy results demonstrated that Zn.MBO@NCHS significantly enhanced the corrosion resistance of the scratched coated samples after 72 hours of immersion, indicating its active inhibitive function.
