Synthesis of bioactive coatings on Ti substrates using glass enamel

Bioactive coatings on titanium can be prepared by dispersing hydroxyapatite particles into a borosilicate glass enamel doped with TiO 2. Adhesion of the coating is obtained when the titanium substrate has been preoxidized before enameling in such a way as to form a continuous TiO 2-layer. Adhesion r...

Description
Summary:Bioactive coatings on titanium can be prepared by dispersing hydroxyapatite particles into a borosilicate glass enamel doped with TiO 2. Adhesion of the coating is obtained when the titanium substrate has been preoxidized before enameling in such a way as to form a continuous TiO 2-layer. Adhesion results from the diffusion of this TiO 2-layer into the liquid glass during enameling. The evolution of the diffusion zone was followed by scanning electron microscopy and electron probe microanalysis. Adhesion disappears after a critical time of firing which corresponds to the completion of the dissolution of the TiO 2-layer by the glass. The borosilicate glass wets the hydroxyapatite particles and adheres strongly to them after cooling.
