Fabrication of Porous Titanium with Biomechanical Compatibility

Abstract:

Article Preview

Porous titanium with good strength and three-dimension pore structure was fabricated by using H2O2 as vesicant foaming titanium powder. The compressive strength, bending strength and Young’s modulus of porous titanium with the porosity of 58vol% are 190.7Mpa, 159Mpa and 4.15Gpa, respectively, similar to that of the nature bone. This kind of porous titanium with good bio-mechanical compatibility may be potential to alleviate the problems caused by the mismatch of the strength and Young's modulus between implant (110 GPa for Ti) and bone. Moreover, the pores (mainly in 100-700µm) are all interconnected and there are many microspores (about 10µm) in the wall of the macrospores. This porous structure would endow the materials with better activity.
