Fabrication and characterization of sol-gel hydroxyapatite-forsterite-bioactive glass nanocomposite coating for biomedical applications

Fabrication and characterization of hydroxyapatite-forsterite-bioactive glass nanocomposite coating was the aim of this work. The sol-gel technique was used to perform hydroxyapatite-forsterite-bioactive glass nanocomposite coating on 316L stainless steel (SS). The X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX) techniques were used to investigate the microstructure and morphology of the coating. Results show that the suitable temperature for calcination was 600°C. At this temperature, the homogenous and crack-free coating could attach to the 316L SS substrate. The result of EDX analysis of hydroxyapatite-forsterite-bioglass coated 316L SS surface indicated the consisting elements of prepared hydroxyapatite-forsterite-bioglass nanocomposite coating and the substrate. Hydroxyapatite-forsterite-bioactive glass nanocomposite coating might be a good candidate for biomedical application.
