Abstract
Nanodiamond particles (ND, 4-6 nm in size) were added to a simulated body fluid (SBF) and electrodeposition (ED) at biological conditions (370C, pH 7.4) was performed on Ti surfaces. The novelty in this work was the addition of the ND particles to the SBF solution used as the electrolyte for the ED of biomimetic HA. The results from Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), coupled with energy dispersive X-ray (EDX) spectroscopy revealed that the Ti surface was covered by white, dense and homogeneous HA layer. X-ray photoelectron spectra (XPS) confirmed the formation of calcium phosphate, calcium carbonate, calcium oxide and hydrated surface layer. The ND particles incorporation yielded increased Vickers hardness of the HA. No cracks were observed in the SEM images of the HA-ND layer, which testifies for its ductility and good residual stress.
