Fabrication and Growth Mechanism of Nanoleaf Sodium Titanate Coating on High-Purity Titanium Surface

摘要

Highly-ordered nanoleaf sodium titanate were successfully synthesized on high-purity titanium surface by catalyst oxidation method. Sodium metaborate powder was coated on titanium substrates, heated in an electric furnace at 650°C for 5 hours and then subjected to a water bath rinse. The structure and morphology of oxide coatings were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results showed that the fabricated coatings were composed of rutile and bamboo-shaped sodium titanate with nano-leval gap, providing the excellent biocompatibility. The mechanism about the growth of highly-ordered nanoleaf sodium titanate also have been discussed in the current work.
