چکیده
Ti(β) alloys have become an important class in the biomedical field due to low Young’s modulus, excellent physical properties, and biocompatibility. However, their like biocompatibility and, also, wear resistance, can be still enhanced. To improve those a composites approach applied. This research shows new of composite structure fabrication by powder metallurgy methods which for stabile yttria-stabilized zirconia (YSZ) reinforcement phase could obtained ultra-fine grain range beta-titanium matrix. In this work, based on ultrafine-grain Ti-xMo (x = 23 wt%, 27 35 wt%) with addition 3 5 wt% or 10 YSZ, 1 Y2O3 were fabricated mechanical alloying hot-pressing approach. Obtained characterized terms composition, microstructure, hardness, surface free energy (SFE), corrosion resistance. The consists phases Ti–Mo, Ti(α), YSZ. oxide tends agglomerate during processing, is revealed Ti23Mo Ti27Mo. Ti35Mo are high degree dispersibility influences significantly hardness value obtained. Only case Ti35Mo, decrease Young’ Modulus observed. All possess hydrophilic property good

متن کاملTransparent nanocrystalline yttria-stabilized-zirconia calvarium prosthesis.
UNLABELLED Laser-based diagnostics and therapeutics show promise for many neurological disorders. However, the poor transparency of cranial bone (calvaria) limits the spatial resolution and interaction depth that can be achieved, thus constraining opportunity in this regard. Herein, we report preliminary results from efforts seeking to address this limitation through use of novel transparent cr...
متن کاملMolecular dynamics simulations of yttria-stabilized zirconia
Oxygen diffusion in the oxygen ionic conductor yttria-stabilized zirconia is investigated by means of the molecular dynamics simulation technique. Oxygen ions migrate by means of a discrete hopping process, mainly between neighbouring tetrahedral sites. Diffusion appears to occur in a short time and a long time regime. Only when the oxygen ions have moved over distances much larger than the cha...

Abstract. Cubic crystalline oxides such as Y2O3 and MgO is used to stabalized zirconia phases at high temperature. In this paper the Y2O3 powder was added to stabilized zirconia and preparing a mixture of MgAl2O4 Spinel by mixing 1mol of nano-MgO with 1 mol of nano-Al2O3 powders. The spinel was added to the Y2O3-ZrO2 by various weight percentage (5, 10, 15, 20 and 25 wt%), and after that the sp...
