摘要
In recent years,a new wave of bioactive,biocompatibility and biodegradable metallic materials were developed for orthopedic applications.Pure Magnesium,Magnesium alloys,Magnesium alloy-based composites are extensive material to the biomedical applications,by virtue of its high biocompatibility and reasonable strength.Pure magnesium,Magnesium alloys can corrode too fast during the physiological conditions and loses their properties before bone heal.The new era for the development of magnesium-based composites can satisfy the orthopedic applications.Magnesium-based composites,as bio-materials,can produce adjustable mechanical properties like Ultimate tensile strength,ductility,elastic modulus,and corrosion resistance in the physiological conditions.In the Mg based composites,the matrix materials are biomedical magnesium alloys base like Mg-Ca,Mg-Al,Mg-Zn,and Mg-REE alloy and The reinforcements are based on hydroxyapatite(HAP),calcium polyphosphate(CPP),andβ-tricalcium phosphate(β-TCP)particles.This comprehensive review is focused on different grades of biodegradable magnesium matrix composites including their mechanical properties and corrosion resistance.
