and evaluations of mechanical properties, biocompatibility and osteogenic ability of sintered porous titanium alloy implant.

A new sintering technique using TiAlV powder suspension was performed to prepare porous TiAlV alloys. The porous alloys could be fabricated with different porosities and pore sizes by controlling the quantity and size of spacer particles added to the TiAlV powder. The characteristics and biological properties of the porous TiAlV with two different porosities were evaluated by mechanical tests, cell tests and implantation. Dense TiAlV was used as the control. Compared with the control group, the porous TiAlV showed good biocompatibility and osteogenic ability, which makes this type of porous alloy a good prospective material for biomedical application. And compared with 50% porosity, the alloy with 75% porosity had the optimal mechanical properties, and suitable pore size and porosity, which allowed more bone ingrowth.
