Porous Ti-6Al-4V Fabricated by Powder Sintering and its Property Evaluation

Abstract:

Porous titanium alloys are frequently used as bio-implant scaffold. In this research, porous Ti-6Al-4V was fabricated by using powder sintering method with ammonium bicarbonate powders as space holder. The space holder decomposes to gases like ammonia, carbon dioxide and water at comparatively low temperature. The advantages of this pore holder and its decomposition products are that they have no contamination to host powders, and harmless to sintering machine. Green bodies with different weight ratio of pore holder and host powder are prepared, and then the pore holders are fully removed by heating at 200°C. Porosity, density, compressive strength and modulus of the sintered porous Ti-6Al-4V are tested.
