properties such as biocompatibility and proper bioactivity response. The aim of the present study was to investigate the bioactivity of wollastonite-hydroxyapatite (WS-HA) bio-nanocomposite for the treatment of orthopedic prosthesis coatings approaches by adding magnetic nanoparticles (Fe3O4; MNPs) and single walled carbon nanotubes (SWCNTs) to the matrix. Bio-nanocomposite coated on AZ91 for 40 minutes at 40 volts using electrophoretic deposition (EPD) and after that the heat treatment performed at 550-650°C for 1 hour. The coats were incubated in simulated body fluid (SBF) and phosphate buffer saline (PBS) for 28 days to detect and confirm apatite-like layer formation. X-ray diffraction (XRD), atomic force microscope (AFM) and scanning electron microscopy (SEM) techniques were used to characterize the phase and morphology of the coated sample. Inductively coupled plasma optical emission spectroscopy (ICP-AES) tests were used to evaluate the concentrations of calcium and silicon ions. The finding from the present study showed the successful coating with 10 wt% MNPs added to the WS bio-nanocomposite with proper biological and chemical properties. Bio-nanocomposite coating can be considered as a suitable candidate for orthopedic coating applications due to its favorable bioactivity.
