Microstructure and mechanical properties of Mg-matrix in situ composites sintered by Spark PlasmaSintering for biomaterial applications

摘要

Recently, Mg-matrix composites gained a great interest as potential candidates for temporary implant applications based on their biodegradability. In addition, magnesium-based materials show their not only biocompatible but also attribute to stimulate bone growth and healing1. So far, there have been many researches on Mg-matrix composites for biomedical applications. However, reinforcements are neither fully biodegradable2 (HA, FA, etc) nor maintain the corrosion resistance of Magnesium (CNTs, Al_2O_3, SiC, etc)3. In order to avoid these problems, there should be solutions for controlling or improving the mechanical and corrosion properties of Mg-matrix composites for biodegradable material applications. Appropriate reinforcements and techniques should be issue of research.
