| Abstract | Electrochemical impedance spectroscopy (EIS) and Tafel plots measurements were employed to evaluate the accessibility of nanolamellate CaTiO3 microstructures in Hanks’ solution. Flower-like CaTiO3 microstructures were formed via the in situ hydrothermal synthesis on a titanium substrate and were superhydrophilic in nature. It had a very high corrosion rate but demonstrated improved biomineralization. The accessibility of solution to the surface was undermined by the modification with a thin hydrophobic silicone layer, which turned the surface to be superhydrophobic. EIS and Tafel measurements results showed that the corrosion rate of the superhydrophobic CaTiO3 surface dramatically decreased with long-term stability in a 3.5 wt % NaCl solution. These Ti/CaTiO3 composite materials can be very useful, especially as surgical implant materials, without hydrophobic modification and can be used as excellent anticorrosion materials after simple modification with a hydrophobic film. |
