| 中文摘要: |
| 为研究热氧化工艺对钛合金表面耐磨性的影响，提高钛合金的表面硬度和耐磨性能，采用热氧化处理技术在钛合金表面生成热氧化陶瓷层，借助电子探针、X衍射仪对热氧化层进行了成分和结构分析。采用MRH-3型高速滑块磨损试验机，在润滑条件下对经热氧化处理和未处理的Ti6A14V合金耐磨性进行滑动．滚动试验。结果表明：热氧化后的T16A14V合金的磨损量明显减少，该热氧化处理方法能显著增强T16A14V合金的耐磨性。根据试验结果和系统分析，讨论了热氧化处理后材料的摩擦磨损机制。 |
| 英文摘要: |
| 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. |
