Developing composites of zinc and hydroxyapatite for degradable orthopedic implant applications

Abstract In the present work, Zn-HA composites were developed by powder metallurgy route targeted for bone implant applicaitons. powders with varying HA content (1, 2, and 4 wt.%) ball milled 1 hr sintered to produce composite compacts. X-ray diffraction (XRD) studies done all No impurities observed in powders. Microstructural observations revealed formation of lamellar structure due plastic deformation Zn during milling. Grain size measurements decreased grain increase addition HA. Furthermore, aspect ratio (length thickness ratio) grains was measured found that also increased content. Higher microhardness compared pure Zn. However, 1% has shown higher hardness remaining composites. Form preliminary observations, it can be concluded successfully produced morphology milling followed sintering biomedical applications hardness.
