Fabrication and characterization of the Ti-6Al-4V/Mg scaffold
Ti–6Al–4V scaffolds were fabricated by powder metallurgical space holder technique in this research. The most added magnesium (Mg) powder was evaporated and a skeleton of Ti-6Al-4V alloy was produced. For this purpose Ti-6Al-4V and Mg powders mixture compacted in a steel die by applying uniaxial pressure of 500 MPa before sintering the green product in a sealed quartz tubes at 900 °C for 2 hour...
متن کاملFatigue of Ti-6Al-4V
Metallic biomaterials have essentially three fields of use; these are the artificial hip joints, screw, plates and nails for internal fixation of fractures, and dental implants. Any of these devices must support high mechanical load and resistance of material against breakage is essential. High mechanical properties are needed for structural efficiency of surgical and dental implants. But their...
متن کاملSolid-state foaming of Ti–6Al–4V by creep or superplastic expansion of argon-filled pores
Ti–6Al–4V foams are produced by the expansion of pressurized argon pores trapped in billets created by powder metallurgy. Pore expansion during thermal cycling (840–1030 C, which induces transformation superplasticity in Ti–6Al–4V) improves both the foaming rate (by reducing the flow stress) and the final porosity (by delaying fracture of the pores and subsequent escape of the gas), as compared...
متن کاملCharacterization of diamond-like carbon films deposited on commercially pure Ti and Ti–6Al–4V
The diamond-like carbon (DLC) films deposited on the articulating surface of medical-grade Ti and Ti–6Al–4V were characterized. The DLC films were synthesized by r.f. plasma assisted chemical vapor deposition (PACVD) using C6H6 at 10 mTorr. For wear tests, the ball-ondisk type wear tester was employed by wearing a 5-mm diameter ruby ball against a rotating metal disk. The DLC coating dramatical...
متن کاملGas nitriding and subsequent oxidation of Ti-6Al-4V alloys
Ti-6Al-4V alloys consisting of α-Ti grains and intergranular β-Ti islands were nitrided at 850°C for 1 to 12 h under a nitrogen pressure of 1 Pa. With increasing nitriding time, the Ti-N compound layer became thicker, and the α-Ti diffusion zone containing dissolved nitrogen became wider. In the Ti-N compound layer, the initially formed Ti2N became TiN as the nitriding progressed. The nitride l...
