Abstract
Bioactive glass coatings based on a novel SiO 2–P 2O 5–CaO–K 2O 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 rather uniform hydroxyapatite layer developed on the coatings, indicating that they may have the potential to faster osseointegration of prosthetic implants.
