It is well known that the wettability of biomaterials is a factor which significantly influences their biocompatibility, as the protein absorption is promoted by superior wettability [66,67]. Figure 7 presents the images of the SBF droplets on the surfaces of the uncoated and coated TNZT substrate, the measured values of the contact angle and the averaged surface roughness Ra.…”

SiC- and Ag-SiC-doped hydroxyapatite (HA) coatings were deposited via magnetron sputtering aiming at increased corrosion protection of Ti-10Nb-10Zr-5Ta alloy in simulated body fluid environment and superior mechanical properties compared to plain hydroxyapatite. The coatings had a total thickness of about 350 nm. The X ray diffraction patterns indicate that HA coatings are polycrystalline with a hexagonal structure and the addition of SiC determined the coating amorphization. All coatings presented a lower roughness compared to the Ti alloy and were hydrophilic. Ag-SiC-HA coating presented the best corrosion resistance and tribological parameters. All coatings were biocompatible, as ascertained via indirect cytocompatibility studies conducted on Vero cells.
