The growing evidence of beneficial role of zinc in bone has increased the interest of developing zinc-containing biomaterials for medical applications and specifically biocompatible coatings that can be deposited on metallic implants to benefit from their load-bearing capabilities. In present work, zinc oxide/cerium, lanthanum substituted (ZnO/Ce,La-HAP) hydroxyapatite bilayer coatings have been fabricated by electrodeposition technique. As developed, ZnO/Ce,La-HAP bilayer coatings were then structurally, morphologically and chemically characterized using Fourier-transform infrared spectroscopy(FT-IR), X-ray diffraction (XRD), higher resolution scanning electron microscopy (HRSEM) and energy dispersive X-ray spectroscopy (EDAX). The properties of corrosion performance of 316L SS were explored in Ringers solution using electrochemical analysis. The potentiodynamic polarization and impedance analysis demonstrated that the anticorrosion behavior of 316L SS was significantly increased by the bilayer coating. Cell viability in vitro, antibacterial activity and live/dead assay of ZnO/Ce,La-HAP bilayer coating were investigated. Hence, development of ZnO/Ce,La-HAP bilayer coating on 316L SS to make it suitable for biomedical applications.
