In the present study we account on the fabrication of duplex layer (Europium substituted hydroxyapatite (Eu-HAP) and Polyindole-5-carboxylic acid (PICA)) coatings on Ti by electrochemical technique. The as fabricated coatings were characterized for its functional groups and morphology by Fourier Transform Infrared Spectroscopy (FT-IR) and scanning electron microscopic (SEM) techniques, respectively. The corrosion resistance performance (i.e., bioresistivity) of the coatings was evaluated by electrochemical characterizations. Further, the biocompatibility of the coatings was characterized by in vitro antibacterial and cell viability. Thus, the as-developed Eu-HAP/PICA duplex coating will be a prospective and promising material for bone implant applications. © 2024 Elsevier B.V., All rights reserved.
