Bio-mechanical characterization of Mg-composite implant developed by spark plasma sintering technique

Abstract In the present research work, degradable Mg-based alloy for bone fixation devices was manufactured using a mechanical alloy-assisted SPS technique. The effect of MA-SPS produced alloys on the morphology, and bio-mechanical properties were investigated. The effect of Hydroxyapatite, sintering temperature and sintering pressures was evaluated. The surface morphology, elemental, phase composition, mechanical properties of SPS fabricated composites were characterized in detail. Hydroxyapatite (HA) was obviously added to the Mg-matrix to modify the Morphology, which has resulted in the observation of coarse porous Mg with HA morphology. In Mg with HA implants, several biocompatible intermetallic phases such as CaMg, Mg-Zn, Mn-CaO, Mn-P, Ca-Mn-O and ZnO2 have been produced, which are beneficial for improved corrosion and bio-activity properties. The elastic 32 GPa modulus is manufactured by SPS compounds Mg-with-HA Alloy.
