Abstract

Titanium substrates were provided with ability of biomimetic apatite deposition in a simulated body fluid by means of chemical treatment and subsequent thermal treatment. Examined were the effects of the chemical treatment time, the concentration and pH conditions of the H2O2 solutions on formation of bioactive titania gel layer and in vitro bioactivity. The optimum process consist of 6 mass% H2O2 treatment at 60 °C for 3-6 h and subsequent thermal treatment at 400 °C for 1h. Reactions between the titanium substrates and H2O2 involved titania gel formation and Ti (IV) dissolution. Each reaction rates well related with the concentration and pH of the H2O2 solutions.
