Technical Paper


In this work, porous tantalum scaffolds (having porosity up to ~ 71%) were prepared via space holder technique at a lower sintering temperature of 1300 °C. Depending on the amount of porosity, the elastic modulus, yield and compressive strength of porous tantalum scaffolds were found to vary in the range of 1–7 GPa, 4–11 MPa and 22–30 MPa, respectively. Finite element simulation results revealed that tantalum scaffolds with 30% porosity were best suited for hip joint replacement applications as the developed von Misses stresses and displacement of implants under given loading conditions were within safe limits for these scaffolds. The electrochemical behavior of scaffolds was evaluated using the electrochemical workstation in simulated body fluid solution, and the corrosion rate of tantalum scaffolds was found to increase from 5.011 to 8.718 mils per year with increasing porosity. These studies reveal that the tantalum scaffolds are very effective for bioapplications.
