Fabrication of Porous Segments Using Ti-۶Al-۴V Chips for Orthopaedic Applications

Different methods have been evaluated for manufacturing the porous Ti۶Al۴V alloys according to decreasing stress shielding phenomenon and increasing mechanical compatibility between the metallic components and the host tissue. For this purpose, in this work Ti۶Al۴V alloy chips were pressed under ۴۰۰ MPa pressure and then samples were categorized and heated into two groups at ۱۰۰۰ and ۱۱۵۰℃ under a vacuum about ۱۰-۴ mbar. The results implied a porosity about ۳۵%, significant reduction of density in prepared segments comparing to bulk ones and a, reduction in the elasticity modulus and better matching with the host cancellous bone tissue. According to the results one can expect to manufacture porous Ti۶Al۴Vorthopaedic and dental implants using the discussed method.
