Chemical and heat treatments of titania nanostructures

Popis výsledku v původním jazyce

Titanium and its alloys are commonly used as biomedical and dental materials. However, they sometimes need a long time to bond directly to living bone. To avoid this phenomenon, various surface modifications are needed. Recently, a possible way to modifythe surface of the titanium substrate is the formation of TiO2 nanotube layers by electrochemical oxidation under specific conditions. Nevertheless, the properties of the tubes can be further modified to enhance bioactivity. The work is devoted to the study of hydrothermal or heat processes leading to the improvement of the bioactivity of titanium nanostructures. Titanium nanotubes were prepared on c.p. titanium (grade 1) in a mixture of glycerine, demineralised water and ammonium fluoride. The influence of heat treatment (500 ? 800°C) on stability and phase composition of nanostructures was tested. The chemical treatment was performed in alkali solutions, namely sodium and calcium hydroxide. Finally, a combination of both methods was
