HA-ZnO-Fe3O4 COMPOSITE MANUFACTURED BY WET POWDER METALLURGY PROCESS FOR IMPLANT APPLICATIONS

A hydroxyapatite (HA) based biocompatible and bioactive composite is an appropriate choice for bio-implants. This ex-perimental work presents the influence of ZnO and Fe3O4 on the microstructure of HA-ZnO-Fe3O4 composites synthesized by the wet powder metallurgy process. These composites were characterized using SEM, energy-dispersive X-ray spectroscopy (EDS), and XRD. The obtained results showed the effect of the addition of Fe3O4 on the interface formation, which is exhibited by interconnected pores and sintered neck in the micrographs. The observed porosity helps to enhance the required osseointegration for the fixation of implants with human bones.
