Development of sol-gel derived hydroxyapatite-titania coatings
Ün, Nusret Serhat; Durucan, Caner; Department of Metallurgical and Materials Engineering (2008)
A processing route for development of hydroxyapatite (Ca10(PO4)6(OH)2 or HAp)-titania (TiO2) hybrid coatings on titanium alloy (Ti6Al4V) has been established. HAp powders of different size and morphology were synthesized by aqueous precipitation techniques using different precursor couples and XRD, SEM and FTIR were performed for complete characterization. Hybrid coatings were then prepared via sol-gel by incorporating presynthesized HAp powders into a titanium-alkoxide dip coating solution. Titania network...
Development of rare earth-free negative electrode materials for NiMH batteries
Onur Şahin, Ezgi; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2016)
Ni/MH battery negative electrodes normally make use of rare earth AB5 compounds. Development of rare earth-free negative electrode materials for Ni/MH batteries is desirable so as to lower the cost, and widen the availability. Although there are a number of alternatives, of these AB2 alloys are particularly attractive, as they offer better capacities than AB5. A major problem in this group of alloys is that they are difficult to activate, i.e. they require a large number of cycles before they could reach th...
Development of high strength lightweight high entropy alloys (LWHEAs)
Polat, Gökhan.; Kalay, Yunus Eren; Department of Metallurgical and Materials Engineering (2020)
In this thesis, the HEA formation ability of low-density elements was carefully studied in detail. In this respect, lightweight or relatively lightweight elements such as B, Mg, Al, Si, Ti, V, Cr, Mn and combinations of these elements with high-density elements such as Cu, Ni were used to produce novel lightweight high entropy alloys (LWHEAs) relative to the density of steel parts (~7.86 g/cm3). This thesis involves the design, production, and characterization of LWHEAs. The design and selection of the prop...
Development of magnesium based negative electrode materials for nickel metal hydride batteries
Eyövge, Cavit; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2017)
Negative electrode materials of the nickel metal hydride (NiMH) batteries generally based on AB5 or similar compounds that make use of rare earth elements. The high cost of these elements makes it necessary to look for other alternatives that are more readily available and of low cost. It is also desirable to aim for materials that would have discharge capacity higher than roughly 350 mAh/g, which is typical of AB5 compounds. Magnesium-based hydrogen storage alloys have attracted considerable attention as a...
