Treść
In this paper, comparative studies of the structural, mechanical and corrosion properties of TiO2-WO3 thin films, with different contents of WO3, have been investigated. The thin films were formed using the electron beam evaporation method, on the Ti6Al4 V surface. The structural characteristics of the thin films obtained, were examined using SEM and XRD measurements. The mechanical properties of the coatings were determined by nanoidentation measurements. The corrosion properties of the thin films were determined by an analysis of the voltammetric curves. The results obtained show that the layer with the highest content of tungsten – (Ti0.41W0.59)Ox is characterised by the best mechanical and corrosion properties from all tested samples. The hardness obtained for this sample was equal to 3.20 GPa, and was similar to the value obtained for undoped TiO2 thin film. In addition, the value of corrosion current density for this sample was equal to 3.6∙10−8 A/cm2, and was similar to the value obtained for pure WO3 thin film.
