Abstract

High oriented TiO2-ZrO2 composite thin films on Si (100) and glass sheet were successfully prepared by sol-gel process followed by dip-coating the ethanol solution of zirconium oxychloride and titanium tetrachloride. The sol-gel process, microstructure, morphology and tribological properties of TiO2-ZrO2 films were investigated using TGA, DSC, XPS, XRD, AFM and dynamic-static tribometer. The results show that the TiO2-ZrO2 films are dense, homogeneous and at a complete tetragonal phase with an excellent antiwear and friction reduction performance. Under 0.5N applied load, the friction coefficient is 0.14-0.20 and the antiwear life is more than 5000 sliding cycles for both TiO2-ZrO2/AISI 52100 steel and TiO2-ZrO2/Si3N4. SEM observation suggests that wear mechanism of TiO2-ZrO2 composite film under low load was fatigue wear, and under high load was adhesive wear. The TiO2-ZrO2 films show potential applications as coatings for antiwear and friction reduction under the harsh condition.
