Erosion resistance of sol-gel TiO2-ZrO2 film on stainless steel

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. Dry silica sand was used as erodent, with 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). Wear scars were analyzed by the scanning electron microscope (SEM). Obtained results showed that erosive wear resistance of the sol- gel TiO2-ZrO2 film significantly depends on the erodent impact angle, while the erosive wear resistance decreases with the impact angle increase.
