Titanium dioxide exhibits many interesting features, which make this material applicable in solar cells, as photocatalyst, humidity sensors, medical implants, as well as in cosmetics, and pharmaceutical products. Recently, titanium dioxide in a form of thin layers deposited on various substrates has been in the centre of interest of tribology. Some tribological properties of titanium dioxide and its composites have been already studied, but in many domains these properties are still not investigated enough. This study focuses on some tribological aspects of titanium dioxide thin films including the influence of such parameters like temperature, surface modification, deposition method and porosity.

First part of this work presents the preparation methods of titanium dioxide thin films deposited on Si wafers. Titanium dioxide was prepared mainly with the use of sol-gel method from the Ti(-OPr)₄ precursor and deposited on silicon wafers with the use of dip-coating method. Titanium dioxide thin films were obtained in non-porous and porous form. Porous samples were obtained with the use of surfactants.

Second part of the investigations presents titanium dioxide surface characterization (surface topography, internal structure, surface properties and friction) performed with such techniques like Atomic Force Microscopy (AFM), infra red spectroscopy (FT-IR), X-ray diffraction (XRD), etc. Tribological properties of the samples were characterized with the use of the microtribometer operating in the load range of 0-100 mN. The coefficient of friction and wear obtained in microtribological measurements were main representative parameters giving information about the influence of temperature, deposition method, porosity and surface morphology on frictional properties of titanium dioxide thin films.
