| Abstract: |
| In order to study the effect of thermal oxidation treatment on wear resistance properties of a titanium alloy and improve the hardness and enhance the wear resistance, the ceramic oxide coating was prepared on Ti6A14V alloy by thermal oxidation in air. The element profile along oxidation layer and the crystal structure were studied by EMPA and XRD. The wear behaviour of thermal oxidation treated as well as untreated Ti6A14V alloy had been investigated using an MRH-3 tribometer in rolling-sliding motion under lubrication conditions. The results show that the treatment can significantly reduce tendency to adhesive wear and enhance the wear resistance of Ti6A14V alloy. Based on the experimental results, in conjunction with systematic analyses, the wear-reduction mechanisms involved in the thermal oxidation treated material were discussed. |
