There is a need for new materials that can stimulate the body’s own regenerative mechanisms and promote tissue healing. Bioactive glasses have high potential as coatings for metallic implants to improve their osteointegration as they stimulate bone cells to produce new bone, they are degradable in the body and they bond to bone.

The aim of this study was to study the formation of calcium phosphate layer on the surface of bioactive glass coatings thermally sprayed.

Coated samples have been characterized by means of X-Ray diffraction (XRD), scanning electron microscopy (SEM) observation, energy dispersion spectrometry (EDS) analysis and bioactivity of the coatings was tested in vitro using a simulated body solution (SBF) at different exposure times.

Bioactive glass coatings can be used to enhance lifetime of the current implants for load bearing applications. This study is the first stage of a larger project of the research group.
