Bioactive glass coatings based on a novel SiO2-P2O5-CaO-K2O system (“Bio-K”) were deposited by the High-Velocity Suspension Flame Spraying (HVSFS) technique. Attrition-milled micrometric powder particles, dispersed in water+isopropanol, were sprayed onto Ti plates. The coatings remained entirely glassy, but the glass underwent some structural alterations during processing. After soaking in simulated body fluid (SBF), a quite uniform hydroxyapatite layer was developed on the coatings, which indicates they may have the potential to favour osseointegration of prosthetic implants.
