Plasma-sprayed Yttria-stabilized zirconia (YSZ) coatings have been used in gas turbines for decades. They are applied thermal insulation to increase operating temperature and hence efficiency component’s lifetime. To keep manufacturing costs low, especially deposition is important. However, increasing it also related a reduction porosity, affecting the insulating properties of layer. find an op...

Zirconia electrodes with dendritic patterns were fabricated by stereolithographic additive manufacturing (STL-AM). A solid electrolyte of yttria-stabilized zirconia (YSZ) was selected for oxygen separation in the molten salt electrolysis aluminum smelting without carbon dioxide excretion. Thereafter, 4, 6, 8 and 12-coordinated structures composed cylindrical lattices designed as computer graphi...

Thermal barrier coatings (TBCs) prolong the durability of gas turbine engine components and enable them to operate at high temperature. Several degradation mechanisms limit TBCs during their service. Since atmospheric plasma spray (APS) processed 7–8 wt.% yttria stabilized zirconia (YSZ) widely utilized for applications are susceptible erosion damage, this work aims evaluate influence porosity ...

A theoretical model is proposed that describes the effect of graphene platelets pullout on fracture toughness ceramic/graphene composites. The dependences concentration and dimensions are calculated using a yttria-stabilized zirconia (YSZ)/graphene composite as an example. Calculations predict if from ceramic matrix dominant mechanism, then maximum achieved in case longest thinnest possible pla...

Currently, ceramics are widely used in various industry branches, especially energy, chemistry, and aerospace, as well medicine. Yttria-stabilized zirconia (YSZ) having unique electrical, thermal, mechanical properties is one of the most popular for such applications. In this study, influence sintering temperature yttria percentage on microstructure behavior YSZ have been investigated. Correspo...

An industrial ceramic thermal-barrier coating designated PWA 266, processed by electron-beam physical-vapor deposition, was measured using a steady-state thermal conductivity technique. The thermal conductivity of the mass fraction 7 % yttria-stabilized zirconia coating was measured from 100 °C to 900 °C. Measurements on three thicknesses of coatings, 170 μm, 350 μm, and 510 μm resulted in ther...

Bacterial adhesion to implant biomaterials constitutes a virulence factor leading to biofilm formation, infection and treatment failure. The aim of this study was to examine the initial bacterial adhesion on different implant materials in vitro. Four implant biomaterials were incubated with Enterococcus faecalis, Staphylococcus aureus and Candida albicans for 2 h: 3 mol % yttria-stabilized tetr...

Ni coarsening in the Ni/yttria-stabilized zirconia (YSZ) fuel electrode of solid oxide cells (SOCs) is a major cause long-term performance degradation. Phase-field modeling powerful tool for studying complex 3D structures SOC electrodes. In this work, we present study aimed at validating phase-field model, comparing simulation results with time-dependent ex-situ tomographic data. Three equilibr...

 This study aimed to investigate the impact of N-vinylcaprolactam (NVC) and Nano-sized yttria-stabilized zirconia (YSZ), separately and simultaneously, on the mechanical properties of the commercial glass ionomer cements (GICs). Methods: The NVC is able to ameliorate the mechanical and surface properties of glass ionomers; however, its effect hasn’t been investigated in conjunc...
