Sažetak
Wear resistance of metallic materials can be improved by modifying their surface with different coating deposition techniques, one of which is a sol-gel technology. In this paper, the erosive wear resistance of a ceramic nanostructured sol-gel TiO2-ZrO2 film deposited on the stainless steel substrate (X5CrNi18-10) by the dip coating technique has been described. Steel balls were used as an erodent, with the impact angle of 30 and 90. The coating thickness, as well as chemical composition after erosion, was analyzed by the Glow Discharge Optical Emission Spectrometer (GD-OES). Obtained results showed that the erosive wear resistance of sol-gel TiO2-ZrO2 films does not depend significantly on the impact angle, if the applied erodents are steel balls. The coating is much harder than the substrate, so it is pressed into the substrate during the steel balls impacting.
