Porous titanium with a pore size of 150-600 microm and a porosity of 67% was prepared by fiber sintering. The porous titanium had a complete three-dimensional (3D) interconnected structure and a high yield strength of 100 MPa. Si-substituted hydroxyapatite (Si-HA) was coated on the surface by a biomimetic process to improve the surface bioactivity. X-ray diffraction results showed that Si-HA coating was not well crystallized. New bone tissue was found in the uncoated porous titanium after 2… CONTINUE READING
