Sol-gel titania and silica thin films have received a great deal of attention in the area of bioactive surface modification of metallic implants. These materials are believed to give rise to an entirely new generation of bone-bonding materials due to their relative ease of production, ability to form a physically and chemically uniform coating over complex geometric shapes, and their potential to deliver exceptional mechanical properties due to their nanocrystalline structure.
In this work crack-free and uniform nanocrystalline titanium and silica pure oxides and Ca-doped oxides thin films were obtained. These materials prepared via sol-gel method and coated by dip-coating method onto the different substrate surface were annealed in air at 1000C, 2000C, 3000C, 4000C and 5000C. The structural properties of the films have been evaluated using X-ray diffraction and Raman spectroscopy. Changes in morphology of ceramic films were observed using scanning electron microscopy.
