Analysing the characteristics of magnesium based composites for biomedical applications

Abstract

Magnesium and magnesium alloys, a new generation of biodegradable metallic materials, have been explored for usage in numerous applications, including the automotive, aerospace, and implant material industries, because of their low densities and good mechanical properties. Magnesium-based materials that are biocompatible and biodegradable have been the subject of numerous successful investigations and are thought to be ideal for orthopaedic applications such as nails, screws, splints, etc. Because magnesium has similar physical and mechanical properties to cortical and cancellous bones (elastic modulus of 41–45 GPa), stress shielding is less likely to occur. Low corrosion resistance is magnesium's main downside, which also affects its mechanical and physical properties when it is in use. This article discusses the various alloying elements with magnesium for improving corrosion resistance and mechanical properties.
