Abstract:

In this study, porous titanium-10 wt.% bioglass nanocomposites were fabricated by the combination of mechanical alloying and a space holder sintering process. The mixed powders were mechanically alloyed for 15 h. The blended Ti-Bioglass was mixed with 30 wt.% carbamide as a space holder. The mixtures were uniaxially pressed and finally, the green compacts sintered at 1150°C for 5 hours. The porous structures are characterized by X-ray diffraction method (XRD) and scanning electron microscopy (SEM). The mechanical properties were examined using micro hardness and compression tests. The investigation revealed that after 15 h of milling, the Bioglass dissolved in Ti lattice. Also, results show that nanostructured Ti-10 wt.% Bioglass with 31.5 nm crystallite size possess greater hardness compared to respective microcrystalline titanium and desirable compressive strength for using in biomedical application.
