Özet
Solo and Combined effect of collagen (COL) and hexagonal boron nitride (h-BN) reinforcement on the corrosion protection, mechanical and tribological properties of electrophoretically deposited hydroxyapatite/chitosan biocomposite coatings are investigated. Crystallographic, surface morphology and topography, spectroscopic, corrosion protection characteristics, thermal behaviour, mechanical and tribological properties of the electrophoretically deposited biocomposite coatings are investigated via XRD, FE-SEM and SPM, FF-IR, Tafel and electrochemical impedance spectroscopy (EIS), thermogravimetric analysis, nanoindentation and nanoscratch techniques, respectively. Both solo reinforcement of collagen and h-BN exhibits positive effect on the corrosion protection, mechanical and tribological properties of the HA/CTS biocomposite coatings. However the combined use of these two supporting materials has had a much more positive effect on the physical properties of the coating thanks to the synergetic effect.
