Fusion of biocompatible glass/ceramic to metal substrate

A method process of fusing a biocompatible and bioactive glass to a metallic substrate, the method comprising:

• a. grit blasting a metallic substrate, comprised of titanium, with aluminum oxide to remove a passivated surface layer of the titanium substrate to minimize the introduction of active foreign particles;
• b. cleaning the metallic substrate thoroughly, after the grit blasting;
• c. creating a suspension of biocompatible and bioactive glass powders in a solvent;
• d. after the cleaning, depositing the suspension onto the metallic substrate with an air brush, until the substrate is fully coated;
• e. drying thoroughly the coated metallic substrate in air in a substantially dust-free environment to assure the integrity of the final coating;
• f. inserting the dried coated substrate into a non-reactive chamber of a furnace with a controlled atmosphere;
• g. purging the chamber with an inert gas to substantially remove any other gas within the chamber;
• h. firing the dried coated metallic substrate, inside the chamber, in the inert gas, to form a covalent bond between the metallic substrate and dried metallic substrate coating;
• and
• i. wherein steps d. through h. are sequential.
