摘要：

By using H2O2 as foaming reagent, porous titanium with open and interconnected pore morphology was obtained. The morphology, pore structure and elemental composition were observed by SEM-EDX. The mechanical property was determined by compressive test. The results show that the compressive strength and Young's modulus of porous titanium with 64% porosity were 102 +/- 10 MPa and 3.3 +/- 0.8 GPa, respectively, and for 76% porosity porous titanium, the values were 23 +/- 10 MPa and 2.1 +/- 0.5 GPa. These results suggest that the former has sufficient mechanical properties for clinical use under load-bearing conditions and the latter has the potential application for tissue engineering scaffolds.
