Abstract

Glasses in the system Si-Ca-Na-Mg-P-K-O with thermal expansions coefficients close to that of Ti6AI4V were used to coat the titanium alloy by a simple enameling technique. Firings were done in air at temperatures between 800 and 840°C and times up to 1 minute. Graded compositions were obtained by firing multilayered glass coatings. Hydroxyapatite (HA) particles were mixed with the glass powder and the mixture was placed on the outer surface of the coatings to render them more bioactive. Coatings with excellent adhesion to the substrate and able to form apatite when immersed in a simulated body fluid (SBF) can be fabricated by this methodology.
