Synthesis of Bio-inspired Mg-HA-MWCNT Porous Composite by Spark Plasma Sintering

In the present research work, an attempt has been made to utilize the potential of spark plasma sintering technique to develop porous Mg-HA-MWCNT composite for scaffold applications. The alloying of HA and MWCNT was carried out using ball mill and sintering was carried out using SPS technique. Morphology, mechanical properties was investigated by FE-SEm and nano-indentation technique. From the SEm, micrograph, the relative density of the synthesized composite was obtained in the range of 85-95 %. The results showed that porous Mg-10HA-MWCNT possessed not only low elastic modulus of 20 GPa (close to that of human bone) but also high compressive strength (35 MPa). Excellent corrosion resistance and bioactivity has been found.
