Summary: The study explores the scale formation behavior of N80 steel in CO2 environments at different temperatures and immersion times. It is found that temperature and immersion time significantly influence the electrochemical behavior, as a result of different scales formed on the steel surface. The presence of CaCO3 inhibits corrosion and the formation of FeCO3, with aragonite CaCO3 providing better protection due to its compact structure.

Summary: The study found that cold rolling of mild steel leads to improved corrosion resistance, indicated by a higher corrosion potential, reduced corrosion current density, and higher impedance in the rolled samples as compared to the unrolled ones. This suggests that mechanical deformation can enhance the corrosion properties of metallic materials.

Summary: This study focuses on improving the working life and performance of spur gears through surface coating. Different coatings, including Al2O3-40%TiO2, Cr3C2-20%NiCr, and WC-10%Co-4%Cr, were applied to a mild steel C45 base material using the detonation thermal spray method. XRD and SEM analysis were performed to confirm material phase and examine surface topography and compositions. The coated specimens were evaluated for their contact stress, bending stress, total deformation, hardness, tensile strength, and wear resistance. The results showed that all the coated materials exhibited enhanced mechanical properties compared to uncoated C45, with WC-Co-Cr coating demonstrating the highest abrasive resistance.

Summary: The inhibitory performance of epoxy polymer (TGETBAU) on mild steel (M-S) in 1.0 M HCl solution was assessed using potentiodynamic polarization and electrochemical impedance spectroscopy. The effects of TGETBAU molecule on corrosion inhibition and the adsorption of epoxy polymer on M-S surface were investigated using density functional theory calculation and molecular dynamics simulation. The highest inhibitory efficiency of 93% was achieved at 303 K with 2.0 g/L of TGETBAU. The corrosion of M-S was inhibited through Langmuir adsorption mechanism. The theoretical calculations were consistent with the experimental results. Moreover, M-S was protected in 1.0 M HCl, as confirmed by scanning electron microscopy and X-ray diffraction analysis.

Summary: The article investigates the high-temperature corrosion of steel S235, concluding that the oxide scale formed at higher temperatures is thicker and more homogeneous compared to lower temperatures. The surface characteristics of the oxidized layers also vary, with the layer formed at 1100 degrees C showing delamination and multiple phases, while the layer formed at 1200 degrees C is compact and uniform.

Summary: New bi-Pyrazol-Carbohydrazides, M2PyAz and B2PyAz, were synthesized and evaluated for their inhibitor effect against mild steel corrosion in 1 M HCl solution. The inhibitory efficiencies of M2PyAz and B2PyAz were found to be high, with M2PyAz showing excellent corrosion inhibition character due to its molecular size and denticity of electron donor atoms. Results from various experimental and computational methods support the conclusion that both M2PyAz and B2PyAz act as effective corrosion inhibitors in the studied system.

Summary: In this investigation, multi-modal characterization was used to evaluate the oxidation of Stainless Steel 304 under laboratory air and 100% steam (1200 degrees C, 2 h). Air oxidation resulted in Fe(NiMn)O4, Fe3O4, Fe(3,0CrxO4, and Cr2O3. Steam oxidation produced a dual layer structure, with a porous outer layer enriched in Fe2O3 and a sub-surface matrix of Fe3O4/Fe(3,0CrxO4 with SiO2/Fe(3_ x)SixO4. Based on these findings, an oxidation mechanism was proposed. The arrangement of oxidation products in air aligned with anticipated diffusion behavior, except for Cr2O3. However, the arrangement in steam deviated due to intergranular interactions with H2O, resulting in the formation of the sub-surface matrix.

Summary: Four novel bis-chalcone-based carbazole derivative photoinitiators were designed and synthesized in this study. Their maximum absorption wavelengths were determined and found to exhibit high molar extinction coefficients. Furthermore, a three-component photoinitiation system including bis-chalcone/iodonium/amine was successfully used to trigger the rapid and efficient photopolymerization of acrylates. The photoinitiators also showed good photo bleaching and biocompatibility, making them suitable for applications such as 3D printing and deep coating curing.

Summary: In this study, 2-amino-5 mercapto-1,3,4-thiadiazole (ATT) was used as an intercalating agent to prepare ATT/BNNS nanofillers via a liquid-phase assisted ultrasound method. TEM results showed that ATT successfully exfoliated BNNS and reduced agglomeration. The WEP ATT/BNNS coating exhibited the best protective performance under saline immersion due to the combined action of ATT inhibitor and BNNS physical barrier.
