Recent advances in magnesium alloys and its composites for bioimplant applications: Processing, matrix, reinforcement, and corrosion perspectives

Abstract

Magnesium alloys have received a lot of attention as prospective bioimplant material due to their biocompatibility, mechanical properties, and biodegradability. Magnesium alloys and composites hold enormous promise as a replacement for permanent metallic implants, as there is no need for secondary surgeries after recovery. To address the corrosion and biodegradation rate of magnesium, different approaches can be adopted, such as composite preparation and surface modification. This comprehensive review emphasizes the processing route, matrix, and reinforcement for Mg alloy and composite, with the aim of enhancing their mechanical, biological, and chemical properties. It also discusses the corrosion and biocompatibility aspects of Mg alloys and composites. The article also sheds light on the potential of magnesium composites to become a dominant player in the field of bioimplant materials.
