Preparation of TiO2 Coating on Pure Ti with Sodium Borate Glass as Catalyst
TiO2 coating was prepared by a novel approach on pure titanium substrates. In this study, we presented a new method to induce the crystal growth of rutile on pure Ti which covered with uniform Na2O·2B2O3 glass powders, and through heating to control the grow process of TiO2 crystal. The results showed that during the heating process, the crystal of rutile grew on the interface between the glass coating and the Ti substrates. To keep the growth of TiO2 crystal controllably, the presence of Na2O·2B2O3 glass powder was essential. Meanwhile, TiO2 crystal grew fast with a higher heating temperature. The mechanism about the growth of TiO2 coating was also investigated in this work.
