Bioactive TiO2 films were deposited on Ti substrates by two-step treatment near room temperature. A well-crystalline TiO2 gel film was obtained on Ti by soaking in TiF4+ H2O2 solution at 60° C for 24 h. Subsequent cathode polarization precipitated calcium hydroxide. Calcium carbonate appeared after samples soaking in a Kokubo simulated body fluid due to the reaction between calcium hydroxide and bicarbonate ions. Calcium hydroxide dissolved into SBF, supersaturated with calcium ions, favored apatite nucleation. Apatite thus deposited without heating the Ti substrates. This method was applicable to substrates other than Ti.
