Abstract
The use of calcium silicate coatings has extensively increased due to properties such as biocompatibility and proper bioactivity response. The present study was aimed to investigate the bioactivity of wollastonite-hydroxyapatite (WS-HA) bio-nanocomposite for the treatment of orthopedic implant coatings by adding magnetic nanoparticles (MNPs) and single-walled carbon nanotubes (SWCNTs) to the matrix. The bio-nanocomposite was coated on Mg substrate for 40 min at 40 V using electrophoretic deposition (EPD), following which the heat treatment was performed at 550–650 °C for 1 h. The coatings were incubated in simulated body fluid (SBF) and phosphate buffer saline (PBS) for 28 days to detect and confirm apatite-like layer formation Inductively coupled plasma-optical emission spectroscopy (ICP-OES) was used to evaluate the concentration of calcium and silicon ions.
