Summary: The formation and structure of passive films on steel in a borate buffer environment pH= 7.4 containing Chloride ions have been thoroughly investigated. The effect of the inhibitor Na-4[ZnNTP]center dot 13H(2)O with a certain molecular structure have been studied, including the mechanism of its action. The lowest anodic dissolution current is reached at the ZnNTP concentration of about 0.6 g/L. At the initial stage of its formation, the passive film is composed of iron oxides, which may further approach the structure of magnetite. Under conditions of counter-diffusion of ZnNTP and Fe2+ ions, the heteropolynuclear complex Zn1/2Fe1/2(H2O)3 mu-H4NTP](n) is formed. As for the character of the formed chemical bonds, steel passivation in the presence of ZnNTP differs significantly from both oxide and salt passivation, and thus should be considered as a specific case, called by coordination passivation.

Summary: This study investigated the corrosion inhibition of L80-1Cr steel by alkanolamine molecules in a CO2-saturated NaCl solution. The results showed that at 20 degrees C, the corrosion rate was more influenced by alkanolamine injection. Experimental and molecular modelling calculations demonstrated that alkanolamine adsorption/desorption played a crucial role in the kinetics and characteristics of FeCO3 formation. Additionally, the efficiency of the inhibitors depended on their chemical structures and adsorption energy on Fe(110), FeCO3(104), and Fe3C(001), with ethanolamine providing the highest efficiency.

Summary: The combination of electrochemical measurement and interface analysis was used to study the interaction between the corrosion inhibitor OMID and carbon steel in 1 M hydrochloric acid. The results showed excellent performance of OMID below the critical micelle concentration, with the interface evolving towards OMID bound to film-free carbon steel as the corrosion rate decreases. This finding is crucial for researchers trying to predict the functionality of corrosion inhibitors and discover next generation chemistries through atomic scale modeling.

Summary: Two triazepine derivatives, AITT and EHTC, were successfully synthesized and demonstrated to be effective corrosion inhibitors for mild steel in 15% HCl medium. The inhibitors showed promising inhibiting performance, with AITT exhibiting higher efficiency than EHTC. The adsorption of the inhibitors on the metal surface played a key role in the protection mechanism. The inhibitors were found to be mixed-type inhibitors, as supported by potentiodynamic polarization experiments and Langmuir Adsorption isotherm analysis. The application of the inhibitors resulted in significant improvement in the damaged surface, as observed through surface topographical analysis. XPS analysis confirmed the presence of the inhibitors on the inhibited metal surface. Computational methods, including Monte-Carlo Simulation, DFT, and Fukui calculations, further supported the experimental findings.

Summary: In alkali-activated slag, the corrosion behavior of reinforcing steel is significantly influenced by the passive film. A 60 nm adsorption aluminate/silicate layer is formed on the surface of the reinforcing steel, while the influence of S2- leads to a less compact passive film with FeS, resulting in lower resistance. However, the reinforcing steel still shows slightly higher charge transfer resistance in the SSP solution due to the barrier effect of the adsorption layer.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: The oxidation behavior of FeCrNi medium entropy alloy was investigated through experimental observations and density functional theory (DFT) calculations. The study found that at 900 degrees C, the alloy forms a desirable and continuous oxide layer, while at 1000 degrees C, the oxide layer becomes discontinuous with penetration of oxide. These observations highlight the significant role of phase structure in promoting the formation of protective oxide scales and influencing oxidation resistance.

Summary: This study presents a new approach to studying the mechanism of filiform corrosion in organic coated steel using the scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM). The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.

Summary: This work explores the correlation between electrolyte transport properties and the variation of pigment volume concentration (PVC) in organic coatings. An odd random phase electrochemical impedance spectroscopy (ORP-EIS) approach is used to analyze the diffusion of ions independent from water uptake. The results show that a higher PVC leads to a more homogeneous coating structure, resulting in faster diffusion of ions and enhanced water uptake.

Summary: The relationship between configurational entropy and lattice distortion in novel rare earth monosilicates was investigated, and the effect of configurational entropy on their properties was studied. The results showed that lattice distortion increased with the increase of configurational entropy, but a highly symmetrical crystal structure was formed when the configurational entropy was large enough, inhibiting the lattice distortion.
