Abstract
Nano-talc was successfully incorporated in the hydroxyapatite matrix via pulsed electrodeposition after being
obtained using an eco-friendly liquid-phase exfoliation process. Scanning electron microscopy, atomic force
microscopy, X-ray spectroscopy, Raman spectroscopy, corrosion and wear resistance, and cytocompatibility tests
were used to characterize the biocomposite ceramics. Talc significantly improves the nanomechanical and wear
properties of bioceramics (i.e., higher stiffness, reduced friction coefficient, and lower wear damage) as well as
corrosion resistance. Talc does not induce cytotoxic activity in in vitro cells and may induce bone maturation as
per biocompatibility tests.
