Abstract:
The TiO
2 film on copper was prepared by using sol-gel technology and hydrothermal treatment. Scanning electron microcopy and X-ray diffraction were used to characterize surface morphology and crystal structure of TiO
2 film. The corrosion resistance and its friction-reducing performance of TiO
2 film were evaluated by polarization curve and friction and wear testing machine, respectively. As comparing to TiO
2 film after conventional calcination at 480 ℃, TiO
2 film after hydrothermally treatment at 170 ℃ showed different surface morphology and crystal structure, lower friction with extended life and better corrosion-resistance.
