Abstract

The purpose of this study was to synthesis gelatin/silicon and magnesium co-doped fluorapatite Nanocomposite coating and also gelatin coating on Ti-6Al-4V alloy in order to improve and modify the biological properties of this alloy. For this aim, Nanocomposite coating and gelatin coating were first fabricated by Dip-coating method. Then, the physical, corrosion and biological properties of the created coatings were investigated by different methods. The results indicated that a uniform Nanocomposite coating with a thickness of about 6. 26 microns was formed with appropriate structure and phases and increased roughness by adding nanoparticles to gelatin coating. Electrochemical measurements showed that nanocomposite-coated Ti-6Al-4V specimen with a polarization resistance of RP = 5. 349×105Ω cm2 has higher polarization resistance in comparison with the gelatine coating with a polarization resistance of RP = 1. 191×105 Ω cm2 and the non-coated specimen with a polarization resistance of RP = 5. 2453×104 Ω cm2. The cytotoxicity test showed no cell cytotoxicity of the coatings. Also, cell growth and proliferation of the nanocomposite-coated specimen showed statistically significant difference compared to the non-coated sample. Cell adhesion to the nanocomposite-coated specimen was also much better than the non-coated sample and gelatin-coated sample.
