Study of biodegradable magnesium metal matrix composite A review

Abstract

Now a Days breakthrough technology for eco-friendly materials products is developed (in orthopedic use as the substrate for implantation of bone), magnesium alloys, because of its suitable strength similar to bone tissue and high compatibility of magnesium and its alloys. Throughout the elevated chloride atmosphere of the physiologic system and the physiological pH(7.4–7.6), pure magnesium will easily corrode. A possible solution to this challenge can be either surface treatment via various methods or alloying of element additions or by the generation of metal matrix composites. The bio-material which is magnesium-based composites can provide resistance against corrosion and adaptable mechanical properties such as elastic modulus, ductility, tensile strength, or combination of these properties and it is the main choice to select magnesium metal matrix composites as opposed to surface treatment methods and alloying of material inclusion. The reinforcing processes are mainly focused on hydroxyapatite, tricalcium phosphate particles, calcium polyphosphate, and mixed tricalcium phosphate particles. In this review article, a detailed analysis of biodegradable magnesium metal matrix composite is discussed briefly.
