Summary: Ni matrix nanocomposite coatings with a microstructure tailored by Cr and graphene particles were assembled at various current densities by electroplating. The tailored microstructure and embedded particles substantially enhanced the corrosion resistance of the Ni-Cr-graphene nanocomposite coating, with the corrosion current density being significantly lower at lower current density due to the strengthened synergistic effect.

Summary: This study investigates the influence of spraying potential on the phase composition, microstructure, hardness, wettability, and corrosion performance of amorphous coatings (ACs) deposited by arc-spraying technique. The results show that ACs with denser microstructure, higher microhardness, lower surface free energy exhibit better corrosion resistance. The corrosion resistance of the coatings is closely related to the surface hydrophobicity, which is mainly governed by the microstructure of the coatings.

The results showed that the addition of graphene significantly improved the hardness and wear resistance of the coatings. Pulse current and pulse reverse current electrodeposited CuNi-G nanocomposite coatings exhibited higher microhardness and wear resistance compared to direct current electrodeposited coatings due to smaller crystallite size, higher graphene content, and lower surface roughness.

Summary: Magnesium alloys are widely used in various industries due to their low density and high strength to weight ratio, but limited by their poor wear and corrosion behavior. In this study, commercial powders of WC-Co and WC-Cr3C2-Ni were thermally sprayed onto magnesium alloy substrates (AZ31 and AZ91) using HVOF spraying. The coatings were analyzed for microstructure and corrosion resistance. The results showed that the coatings had a dense microstructure with typical porosity for HVOF sprayed coatings, and small cracks and unmelted carbide particles were observed. The corrosion resistance of the magnesium alloys was improved by all coatings, with WC-Co providing better protection than WC-Cr3C2-Ni.

Summary: In this study, composite coatings of Ni60AA, Ni60AACu, Ni60AACuMo, and Ni60AACuMoW were prepared by laser cladding. The influence of alloying elements on the microstructure and properties of the coatings was investigated in detail. The coatings consisted of gamma-FCC + Cr-rich phases + Ni-based FCC phase/(Ni3B + Ni2Si) eutectics. Addition of 2 wt% Cu reduced the Cr-rich precipitates and refined the eutectics. Ni60AACu coating exhibited the best wear and corrosion resistance at room temperature and 600 degrees C. Addition of 2 wt% Mo promoted the segregation of Cr and Mo, leading to the formation of coarse Cr-rich precipitates and reduced wear and corrosion resistance. Addition of 2 wt% W promoted the formation of the WC phase, consuming C element and inhibiting the precipitation of Cr and Mo-rich carbides. At 600 degrees C, Ni60AACuMoW outperformed Ni60AA and Ni60CuMo in terms of wear resistance.

Summary: A multi-step green synthesis method without DMF was successfully utilized to fabricate methylammonium lead triiodide perovskite films on mesoporous TiO2/FTO conductive glass substrates. The perovskite films produced through cyclic voltammetry deposition of PbS demonstrated comparable properties to those prepared by conventional methods, with a power conversion efficiency of up to 7.72% under standard conditions. The approach shows potential for enhancing efficiency of perovskite solar cells by eliminating pores and further modifying the electrodeposition process.

Summary: A design concept of phase-separated amorphous nanocomposite thin films is presented that enables interfacial resistive switching in hafnium oxide-based devices. By incorporating an average of 7% Ba into hafnium oxide, films consisting of amorphous HfOx host matrix interspersed with Ba-rich nanocolumns are formed. The resistive switching is restricted to an interfacial Schottky-like energy barrier, which can be tuned by ionic migration under an applied electric field. The resulting devices exhibit stable reproducibility and switching endurance, allowing for multiple intermediate resistance states and synaptic spike-timing-dependent plasticity.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
