Abstract

This paper focuses on the biomedical implants of bone plates with biodegradable Magnesium composites. ZK30 Mgalloy metal matrix reinforced with five weight fractions ofHydroxyapatite (HAP), have been fabricated using powder metallurgy manufacturing process followed by hot extrusion process. Properties such as Tensile and compression tests were investigated. Scanning Electron Microscopy (SEM) techniques were used for surface fracture analysis. The results obtained shows that the maximum ultimate tensile strength was attained at ZK30 Mg alloy while the least was noted for ZK30/10wt%HAP. In addition, ZK30/2wt%HAP shows a higher ultimate compressive strength. The SEM images of tensile specimen displays ductile fracture for ZK30 Mg alloy and quasi cleavage fracture for Mg composite whereas the compressive specimen indicates ductile fracture for ZK30 Mg alloy and Mg composites. The composite exhibited excellent mechanical properties thereby it can be used for biomedical implants of Bone plates.
