Summary: Plasma electrolytic oxidation (PEO) coating on Zr alloy was prepared and investigated under 400°C/10.3 MPa steam condition. The results showed that the PEO coating after corrosion exhibited typical pores and pancake structure features, with decreased surface roughness. The PEO coating corroded for 45 days showed the best electrochemical performance due to the repair of pores and cracks in the oxide/metal interface. However, the corrosion resistance of the PEO coating decreased with longer corrosion time, as the microcracks connected to form larger transverse cracks, allowing the corrosion media to access and oxidize the substrate.

Summary: Al2O3 coatings produced by PEO provide excellent corrosion and wear resistance, but their fracture toughness is limited due to the brittleness of the oxide ceramic. Incorporating ZrO2 into alumina to form ZTA can enhance the fracture tolerance. In this study, an Al2O3-ZrO2 composite coating was successfully applied on a 6082 aluminum alloy, and the incorporation of ZrO2 resulted in a thicker coating with improved passivation and higher fracture toughness.

Summary: The thermographic properties of Cr3+-doped Al2O3 coatings created by plasma electrolytic oxidation were investigated. The coatings were found to be dense and uniformly distributed over the aluminum surface, with room-temperature photoluminescent measurements revealing specific emissions typical for Cr3+ in Al2O3 octahedral configuration. Temperature information was obtained from the coating's emission, with maximal sensitivities observed for different temperature-induced changes in the emissions.

Summary: The surface morphology, phase composition, microstructure, and element distribution of the plasma electrolytic oxidation (PEO) coating on Zirconium (Zr) alloy after corrosion under 400°C/10.3 MPa steam conditions were analyzed. The presence of a compact oxide layer on the PEO coating reduces corrosion weight gain by preventing the corrosion media from entering the substrate. The high compressive stress in the PEO coating leads to the formation of a compact oxide layer, favorable for the nucleation of t-ZrO2 grain and inhibiting phase transformation, resulting in reduced volume expansion and defects.

Summary: The study examined the surface morphology, structure, composition, and corrosion-protective ability of the coatings formed on a zirconium alloy through plasma electrolytic oxidation. A predominantly tetragonal phase of zirconia was formed in coatings at a current density of 30 A/dm(2). Increasing the current density to 40 A/dm(2) promoted the formation of a coating surface layer containing submicron yttria particles.

Summary: Plasma electrolytic oxidation (PEO) is a method to obtain high-quality coatings on aluminum and other metal alloys. Luminescent PEO coatings are a relatively new field, and one approach is to detect ionizing radiation using doped alumina coatings. This study presents an improved method by doping alumina with chromium using citric acid as an additive in the electrolyte. The use of citric acid also allows for the formation of an energy trap in the material, making it possible to measure ionizing radiation using the coating's thermoluminescence.

Summary: Studies on synthetic NiAlCr-Ca and NiAlCr-Sr alloys revealed that the alloy containing Sr showed the best oxidation resistance, while the presence of Ca decreased oxidation resistance due to the formation of non-protective complex oxides and consumption of α-Al2O3 scale. The oxide scale on the Sr-containing alloy mainly consisted of α-Al2O3 phase with Sr-rich nodules, leading to minimal scale spallation compared to the Ca-containing alloys.

Summary: Two-dimensional transition-metal carbides and nitrides (MXenes) have shown promising sensing capabilities, but suffer from weak gas-molecule adsorption limiting their sensitivity and selectivity. Through Au-decoration, MXenes exhibit enhanced response and selectivity in detecting VOCs, especially formaldehyde, with a low detection limit of 92 ppb at room temperature. Au-Ti3C2Tx sensors offer reliable gas response, low noise level, ultrahigh signal-to-noise ratio, high selectivity, and parts per billion level detection of formaldehyde.
