Sažetak

Wear resistance of metallic materials can be improved by modifying their surface with different coating deposition techniques, one of which is the sol-gel technology. The sol-gel technology is simple, easy to adopt, requires low processing temperatures and leads to a high degree of purity of oxide coatings. In this paper, the erosive wear resistance of a ceramic nanostructured sol-gel TiO2-ZrO2 film consisting of three layers, deposited on a stainless steel substrate (X5CrNi18-10) by means of the dip coating technique has been studied. Quartz sand was used as an erodent with an impact angle of 30deg. Quantitative Depth Profile (QDP) analysis was used for the determination of the coating thickness and chemical composition before and after solid particle erosion. Glow Discharge Optical Emission Spectrometry (GDOES) was used for the analysis of the chemical composition of the bulk material (substrate) and the quantitative depth profiling of the deposited sol-gel film. The obtained results show that solid particle erosion of nanometric films can be monitored by depth profiling of the deposited sol-gel film.
