Abstract
- In order to investigate the performance of titanium oxide ceramic layer prepared by a single electrolyte system, a titanium oxide ceramic film was prepared on the surface of titanium using NaOH as electrolyte. The effects of current density and NaOH concentration on phase composition, micromorphology, oxide film thickness, hardness and wear resistance were investigated. Results showed that the phase composition, micromorphology, oxide film thickness, hardness and wear resistance were greatly affected by current density and NaOH concentration. With the increase of current density, the content of rutile titanium oxide in the film increased, the surface morphology became rougher, the porosity increased, the film became thicker, and the hardness increased obviously. With the increase of NaOH concentration, the content of rutile in the micro-arc oxidation film increased, the surface morphology became rougher, the porosity and thickness increased, the hardness increased significantly, and the wear resistance changed without obvious regularity.
