Summary: Fe-20Mn-11.5Al-1.4C-5Cr lightweight stainless steel (LWSS) has equivalent or better resistance to pitting corrosion compared to Fe-11Cr stainless steel (SS), which can be attributed to its protective passive film with higher Cr and Al content, thicker thickness, and lower concentration of point defects.

Summary: This study aimed to locate cobalt in stainless steel and investigate its release behavior in different body fluids. The results showed that cobalt was uniformly distributed with metallic nickel beneath the surface oxide and co-released with other metals during surface reformation and passivation. Exposure to phosphate buffered saline resulted in the incorporation of both cobalt and phosphate in the oxide.

Summary: A combination of X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, and electrochemistry was used to investigate molybdenum and chromium enrichment of a passive film on a model austenitic stainless steel single crystal, as well as the effect of thermal pre-oxidation at 250 degrees C on the film's composition and layering. The study found that pre-oxidation promoted the hydroxylation of chromium and molybdenum, leading to enrichment of these elements in the oxide film, with an increase in both thickness and chromium content of the inner layer under anodic polarization. Additionally, pre-oxidation at 250 degrees C was found to protect against active dissolution during anodic passivation and promote molybdenum enrichment in the outer layer of the passive film.

Summary: This study compared the corrosion resistance and passive properties of CoCrNi medium-entropy alloy and 316 L stainless steel in a simulated marine environment. The results showed that CoCrNi MEA has superior anticorrosion resistance due to its microstructure and surface passive film. The presence of oxide inclusions led to micro-galvanic corrosion and the selective dissolution of Co and Ni elements in the alloy.

Summary: This research investigates the complex effects of hydrogen charging on crystal defects and passive film properties in high-defect-density 443 ultrapure ferritic stainless steel. It reveals that increasing the hydrogen charging current density results in higher hydrogen capture when non-saturated hydrogen is present at hydrogen traps. These captured hydrogen atoms fill the defects, thereby reducing the stress level and promoting the growth of chromium oxides within the passive film. As a result, the alloy's resistance to intergranular corrosion is improved.

Summary: The effect of aging treatment on the microstructure and corrosion behavior of a high-nitrogen stainless steel (HNSS) was investigated. The aging treatment led to the precipitation of Cr2N particles along the grain boundaries, and the morphology changed from dispersive particles to a continuous network. Aging time had minor effects on corrosion potential and corrosion current density, but resulted in a sharp decrease in the pitting corrosion potential. The passive film behaved as a n-type semiconductor, and the donor density of the passive film increased with aging time. However, the fraction of stable oxide (Cr2O3) in the passive film decreased with aging time. The aging treatment weakened the corrosion resistance of HNSS by deteriorating the protectiveness of the passive film.

Summary: The selective corrosion mechanism of CoCrFeMoNi HEA in the transpassive region was studied using electrochemical tests and ToF-SIMS. It was found that Mo and Cr oxides are more enriched in the local passive films formed on the mu and sigma phases than those formed on the FCC phase. As the applied potential increases, the passive film thickens, while the Mo and Cr content decreases, leading to passive film degradation. The local passive films formed on the FCC surface are more susceptible to dissolution in the transpassive region due to the lower content of Cr and Mo in the FCC films. Therefore, selective corrosion of FCC phase occurs in the transpassive region.

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.
