This review article summarizes the use of biodegradable magnesium metal matrix composites in biomedical implants and discusses the effects of reinforcing materials' reactions with the matrix and synthesis processes on the material properties.
The current medical implants are being developed using materials like Co-Cr, stainless steel, and titanium alloys. These conventional implant materials induce a stress shield effect and toxic ions for many medical implant conditions. This leads to secondary oper-ations, which are done to remove the implant. Many researchers have proposed a biode-gradable magnesium metal matrix composite (Mg-MMC) as an implant material to prevent secondary operations. Magnesium composites are subjected to different engineering ap-proaches such as reinforcing elements, surface treatment, and changing synthesis pro-cesses to increase their biocompatibility and mechanical properties. In this context, this review article summaries the influence of various reinforcing materials' reactions with matrix and synthesis processes on the microstructure, mechanical characteristics, and corrosion behavior of biodegradable magnesium matrix composites. This paper aims to provide academicians, industry personnel, and researchers with a comprehensive under-standing of biodegradable Mg-MMC used in biomedical implants. (c) 2022 The Author(s).
