Abstract
Two layer glass coatings on Co-Cr implant alloy were prepared using a simple enameling technique. Their glass composition and its optimum condition (temperature and time) were presented in order to fabricate homogeneous coating with good adhesion to the allay. Glass coatings with glass A (49.8SiO2-15.5Na20-4.2K20-15.6CaO-8.9MgO -6.0P2O5 wt%) and glass B (48.4SiO2-14.7Na20-5.2K20-20TiO2-11.7 (RO, R2O3 , RF2) wt%) were fired at 750°C for 2 min in air and showed excellent adhesion. The glass coatings with excellent adhesion to the substrate and to form Hydroxyapatite when immersed in a simulated body fluid (SBF) for 30 days can be fabricated.
