Summary: This study investigated the feasibility of depositing graphene nanoplatelet-reinforced yttria-stabilized zirconia composite coatings using suspension plasma spraying. The presence of graphene nanoplatelets in the composite coatings was confirmed by Raman spectroscopy and the desired microstructure was observed through scanning electron microscopy analysis. The thermal stability of the graphene nanoplatelets in the coatings was studied by subjecting them to different isothermal treatments, and it was found that the graphene nanoplatelets were retained up to a temperature of 500 degrees C with an increase in defect concentration.

Summary: By investigating the variation of grain boundary energy, the characteristics of grain boundaries in 8% yttria-stabilized zirconia were identified, with a focus on the impact of [100] orientation and [100] twist boundaries. The study results indicate that by manipulating the microstructure to increase the relative areas of [100] twist boundaries, the oxygen ion conductivity of the material can be enhanced.

Summary: Aerosol deposition (AD) is a coating technique where particles are impacted onto a substrate at reduced pressures, leading to consolidation. By synthesizing particles in the gas phase, size-controlled ceramic particles can be injected into AD systems, eliminating the need for aerosolization. The combined use of ultrasonic spray pyrolysis (USP) and AD results in thick yttria-stabilized zirconia (YSZ) coatings with high thermal conductivities.

Summary: Partially stabilized zirconia ceramics with different gadolinia content were prepared by co-milling, spray granulation, axial pressing, and pressureless sintering. The redistribution of stabilizers at high sintering temperatures was observed by XRD. Substituting gadolinia for yttria reduced the stabilizer content in the tetragonal phase and increased the tetragonality, transformability, and toughness of the materials, while decreasing the hardness. The cubic content increased with increasing gadolinia content, as predicted by thermodynamic considerations.

Summary: In this study, cellulose nano crystals (CNC) were used as a dispersant in water-based suspensions of zirconia to investigate their stabilization in ceramic processing. The optimal pH value and minimum CNC concentration for producing stable highly concentrated suspensions were determined. The adsorption of CNC nanofibers around the zirconia particles was observed by scanning electron microscopy (SEM), which contributed to the achieved stability. The suspensions with the lowest viscosity and highest stability were obtained with 30 wt% zirconia particles at pH 4 and 1 wt% CNC.

Summary: This study investigates the influence of mechanically induced dislocations on the electrical conductivity and oxygen transport in YSZ. Distinctly aligned regions with abundant and deficient dislocations are generated using advanced mechanical deformation methods. Electrical characterization reveals highly conducting effects of dislocation-induced strain within the material. Targeted oxygen tracer diffusion experiments confirm the enrichment of oxygen incorporation within the dislocation bundles. Therefore, mechanically induced dislocations have the potential to serve as a design element for tuning bulk ionic transport in YSZ.

Summary: This study measured the elastic constants of plasma-sprayed yttria-stabilized zirconia (YSZ) coatings under different processing conditions and found that the layered structure of the coatings influenced the elastic anisotropy. The dependence of elastic constants on heat-treatment temperature showed a slight increase followed by a decrease. This was attributed to the different effective sintering temperatures of inter-splat pores and intra-splat cracks.

Summary: In this study, Ti-xFe (x = 3,5,9 wt%) alloys were surface modified by micro-arc oxidation (MAO) to improve their antimicrobial properties and biocompatibility. The results showed that increasing the oxidation voltage greatly enhanced the roughness and hydrophilicity of Ti-xFe-MAO alloys. The Ti-xFe alloys micro-arc oxidized at 250 V and 300 V exhibited improved corrosion resistance and excellent antimicrobial and cytocompatibility properties, making them suitable for orthopedic implant materials.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
