| Popis: |
In this work perspectives of a high intensity ultrasound nanostructuring of a titanium surface have been shown. A possibility of a crystal size regulation is determined by the sonication duration and a nature of the electrolyte used. It is interesting to note that the change in crystal size of titanium is not monotonous. There are crystallite size oscillations depending on time of ultrasonic treatment caused by two simultaneous processes of atomic diffusion and melting process in the metal. Oxidative medium, besides having influence on titanium crystallite size, induces the formation of porous photoactive coatings based on the titanium dioxide. These porous coatings are highly rough and hydrophilic. Due to all above properties the metal-oxide structures are perspective as biomaterials for regulating cell adhesion and tissue growth in microdefects for a new generation of implants. |
