moreThe research goal of this experiment is a successful electrodeposition of cerium/europium substituted
hydroxyapatite (Ce/Eu-HAP) on borate-passivated 316L stainless steel (SS). The surface characteristics of the resultant coatings
were evaluated by Fourier transform infrared spectroscopy, X-ray diffractometry, scanning electron microscopy, and energy
dispersive X-ray analysis. The electrochemical characterization of all the coatings was studied in Ringer’s solution, in which Ce/
Eu-HAP coating exhibited better anticorrosion property than the other developed coatings. The metal ion release from the
coatings was studied by inductively coupled plasma atomic emission spectrometry. With regards to antimicrobial activity against
E. coli, the Ce/Eu-HAP coating exhibited high resistivity compared with the other developed coatings. The resultant coatings
exhibited lower cytotoxicity against human osteosarcoma MG63 cells at various incubation days, which evidence the better
bioactive nature of the coatings. Thus, the dual-minerals-substituted HAP coating can play a significant role in biomedical
applications.
