Abstract Scope |
Magnesium and its alloys have often been evaluated for their application as temporary orthopaedic implants owing to several salient advantages over other light metals (aluminium and titanium) such as high specific strength, natural availability, non-toxic nature, similar elastic modulus as that of bone amongst others. However, its limited corrosion resistance restricts its application in real-time biomedical applications. By alloying with biocompatible elements, high corrosion rate can be alleviated without inducing any apparent toxicity in the host both at the local and systemic level. In this study, a novel magnesium-based alloy is synthesized using disintegrated melt deposition and the effect of the secondary extrusion process on the mechanical and corrosion response is studied. Mechanical properties like microhardness and compression displayed excellent results owing to superior grain refinement post extrusion. Corrosion rates evaluated using simulated body fluid(HBSS) displayed promising results with delayed and uniform degradation profile. Strucutre-property correlations are analyzed. |
