Abstract
Titanium and its alloys are widely used in medicine thanks to their favorable physical, chemical properties and relatively good biocompatibility with human cells and tissues. A serious disadvantage of titanium alloys is the metal ions release in contact with body fluids and their penetration into the surrounding biological environment. So as to limit the corrosion and diffusion of its products and improve the implant-bone integration, the metallic substrate is covered with protective layers. One of the methods of applying coatings is the sol–gel technique which allows the incorporation of antimicrobial ingredients into a pure silica matrix. The aim of the study was to assess the stability of hybrid coatings on a titanium substrate during long-term incubation in distilled water and in systemic conditions. The surface properties of the modified TiAlV substrates, i.e., roughness, wettability, and surface energy, were investigated. The chemical stability of the layers in in vitro and ex vivo SEM-EDS and FTIR conditions was also analyzed. For 90 days, a decrease in the contact angle and the roughness increase were observed. The obtained results correlated with the bands intensity decrease in the FTIR spectrum, which confirmed the degradation of the obtained layers in the aqueous environment.
