A relationship between microstructure and the tribological properties of Apatite-Wollastonite glass ceramics (A-W GC), fabricated by different techniques of melt casting and powder packing processing, was studied. The surface crystallization of wollastonite caused a unique surface strengthening in an A-W GC prepared by the melt casting process. The wear rate did not vary between the free surface and interior in an A-W GC made by the powder packing process, whereas an increase of the wear rate with an increase in the distance from the free surface was detected in an A-W GC fabricated by the melt casting process. However, the melt casting process resulted in a higher wear resistance in an A-W glass ceramics for prosthetic applications.


Effects of gold-induced crystallization process on the structural and electrical properties of germanium thin films
Kabacelik, Ismail; Kulakci, Mustafa; Turan, Raşit; ÜNAL, NURİ (Wiley, 2018-07-01)
Gold-induced (Au-) crystallization of amorphous germanium (-Ge) thin films was investigated by depositing Ge on aluminum-doped zinc oxide and glass substrates through electron beam evaporation at room temperature. The influence of the postannealing temperatures on the structural properties of the Ge thin films was investigated by employing Raman spectra, X-ray diffraction, and scanning electron microscopy. The Raman and X-ray diffraction results indicated that the Au-induced crystallization of the Ge films ...

TiN and (Ti,Mg)N thin film coatings were deposited on Ti substrates by an arc-physical vapor deposition technique. The effect of cell presence on hydroxyapatite (HA) formation was investigated using surfaces with four different Mg contents (0, 8.1, 11.31, and 28.49 at.%). Accelerated corrosion above 10 at.% Mg had a negative effect on the performance in terms of both cell proliferation and mineralization. In the absence of cells, Mg-free TiN coatings and low-Mg (8.1 at.%)-doped (Ti,Mg)N surfaces led to an e...
Effect of microcapsulated red phosphorus on flame retardant, thermal and mechanical properties of thermoplastic polyurethane composites filled with huntite&hydromagnesite mineral
ATABEK SAVAŞ, Lemiye; Deniz, Tugba Kaya; Tayfun, Umit; DOĞAN, Mehmet (2017-01-01)
The effect of microcapsulated red phosphorus (mRP) was studied on the flame retardant, thermal and mechanical properties of thermoplastic polyurethane (TPU) composites containing Huntite&hydromagnesite (HH). The flame retardant properties of TPU based composites were investigated using limiting oxygen index (LOI), vertical burning test (UL 94), thermogravimetric analysis (TGA) and mass loss calorimeter. The mechanical properties of composites were studied using tensile test and dynamic mechanical analysis (...
Effect of Cu addition on the microstructural constituents and mechanical properties of twin roll cast AlFeMnSi alloys
Meydanoglu, Onur; Birbaşar, Onur; Ulus, Ali; Beyhan, Bariş; Kalay, Yunus Eren (2015-01-01)
In this study, the effect of copper addition on microstructural evolution, mechanical and corrosion properties of twin roll cast (TRC) AlFeMnSi alloy system mainly used in container foil applications was investigated. Microstructural characterization studies were conducted on as-cast, homogenization annealed and final products by employing optical and scanning electron microscopes. The mechanical properties of the samples obtained from compositional were determined at the thickness of final product by tensi...
Effect of chemical composition on the optical properties and fracture toughness of transparent magnesium aluminate spinel ceramics
Dericioğlu, Arcan Fehmi; Dlouhy, Ivo; Kagawa, Yutaka (2005-05-01)
Polycrystalline transparent magnesium aluminate "spinel" ceramics were fabricated by hot-pressing and hot isostatic pressing (HIPing) using commercially available MgO and Al2O3 Powders. Al2O3 content of spinet was systematically changed that can be expressed as MgO.nAl(2)O(3) with n = 1.0, 1.5 and 2.0. UV/visible and near-IR wavelength region light reflection and transmission behaviors of the spinet ceramics were quantitatively correlated to their microstructure to account for the optical quality of the fab...
