  • Abstract

    Development of terbium/gadolinium dual substituted hydroxyapatite on 316L stainless steel (SS) have been studie. The coatings were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX). The electrochemical results show that the Tb/Gd-HAP coating on 316L SS possesses greatest corrosion resistance in Ringer?s solution. The antimicrobial performance was studied for the obtained coatings against the pathogenic bacterial strains S. aureus and E. coli. The in vitro cell adhesion test revealed that the Tb/Gd-HAP coating was found appropriate for the formation of new cell growth which proves the enhanced biocompatible nature of the coating. Thus, the Tb/Gd-HAP coating on 316L SS can play a key role in the biomedical applications
