A Review of Magnesium Based MMC Fabrication Techniques for Biomedical Applications

Abstract

The magnesium is selected for the future implants material due to its excellent biocompatibility behavior. The biodegradable and biocompatible nature of Mg and its alloy make it prime choice for the development of bio-implants. The mechanical properties of Mg are similar to natural human bone therefore it can be used for temporary implantation for supporting a fracture bone. The rapid biodegradation of pure Mg before the healing time, raise the requirement to develop a metal matrix composites of Mg. The prominent technique of MMC fabrication is friction stir processing (FSP). The FSP is widely used for fabrication of surface composites and also used for grain structure refining and strengthening. The current article reviewed the various surface composites of Mg developed by FSP for alteration of biodegradation and mechanical properties. .
