Synthesis and Study of Properties of Bioactive Glass (45S)/TiO2/Fluorapatite Nanocomposite

Bioactive glasses are widely used as coatings for bone remodeling and metal implants due to the ability to bind chemically and physically with the bone. Using of bioactive glass in composite coatings not only will increase chemical properties. The use of bioactive glass nanopowders in composite coatings, in addition to improving the chemical properties and increasing the biocompatibility of the extinctions in the body, due to the inherent hardness of the glass, also increases the strength of the coating. In this study, coatings containing bioactive glass were synthesized in Nano scale using a mixture of raw materials, and by dipping method one or more layers coated onto plates Titanium. On the other hand, in order to investigate more accurately the effect of vitreous glass and fluorapatite on the composition of the composite, various amounts of these materials were used in coating preparation. The chemical and mechanical properties of the coated specimens in body simulated solution (SBF) were investigated by XRD, SEM, PSA and FTIR. SEM images and X-ray diffraction analyzes (XRD) showed that the apatite layer is formed on the surface of the coating after immersion in the SBF. The formation of this layer increases with increasing immersion time in the SBF and increasing the amount of bioactive glass and fluorapatite. Finally, for the nanoparticles produced in this paper, the degree of hardness was studied in terms of the number of coated layers.
