Summary: This article examines the machining of polymeric materials polypropylene (PP) and un-plasticized poly vinyl chloride (PVC-U) using waterjet technology after surface treatment with polyurethane and acrylate coatings. The study found that abrasive waterjet (AWJ) technology was more efficient compared to waterjet without abrasive (WJ) technology, especially at a cutting head traverse speed of 50 mm·min(-1). Uniform cuts were achieved with AWJ technology, while WJ technology resulted in nonuniform cutting gaps and significant burrs.

Summary: In this study, reduced activation ferritic/martensitic steel F82H samples with tritium permeation barriers were annealed in contact with ceramic breeder pebbles at temperatures of 550 degrees C and 700 degrees C for up to 32 days. The results showed that diffusion kinetics of oxygen and lithium followed Fick's first law of diffusion, and the impurity concentrations in the system and the coating thickness affected the coating compatibility in solid breeder blanket environments.

Summary: A hybrid hierarchical coating (HHC) biodegradable system was developed on Mg3Zn0.4Ca alloy and evaluated under quasi-in vivo conditions. The HHC system improves the corrosion resistance by 10-12 times compared to the stand-alone PEO coating and can be further functionalized with pharmaceutical agents due to its inherent porosity.

Summary: The corrosion resistance of acid-doped polyaniline/epoxy coating on AZ91D has been investigated. The doped polyaniline facilitates the formation of oxide films on the Mg substrate, resulting in a double-layer structure. These oxide layers contribute to the pronounced corrosion resistance of the coating/Mg system.

Summary: The development of biodegradable implants using magnesium alloys faces challenges such as fast degradation, hydrogen gas generation, and pH value elevation in body solution. Surface modification is a practical approach to improve corrosion resistance and enhance bone regeneration and cell attachment. Metal coatings, ceramic coatings, and permanent polymers have been shown to minimize degradation rates, but bioabsorbable polymers are generally preferred for their desired biocompatibility.

Summary: The synthesis of nanoporous zinc oxide films is achieved by infiltrating polymer templates that have different interactions with metal oxide precursors. Gas phase and solution phase precursors are used to study the polymer infiltration process. The properties of the synthesized metal oxide coatings are analyzed using quartz crystal microbalance, X-ray diffraction, and X-ray photoelectron spectroscopy. The surface termination of ZnO films is affected by the polymer type, while the crystallinity is influenced by the precursor state.

Summary: A series of MgO coatings with increasing thickness were prepared by atomic layer deposition, and the influence of coating thickness on SEY was systematically analyzed. Experimental results showed that SEY increased with coating thickness, but almost remained constant beyond a certain thickness. A SEY semi-empirical theory was utilized to explain the SEY regularities of MgO coatings.

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.
