| 目的 研究TC4钛合金基体表面织构设计对类金刚石薄膜(DLC)的摩擦学性能影响。方法 利用激光加工和物理气相沉积组合技术，在TC4钛合金表面制备凹坑织构阵列与DLC薄膜的复合结构，研究其在甘油溶液下的协同摩擦学性能。通过微观划痕和纳米压痕试验对织构化DLC薄膜进行力学性能表征，利用ABAQUS对有无织构下DLC薄膜的失效过程进行仿真对比分析。结果 表面织构可以有效地增加TC4表面DLC薄膜“低摩擦”效应的作用时间，延长其使用寿命。不同织构参数设计对DLC薄膜耐磨时间有显著影响，其中直径200 µm、面积率20%的织构化DLC薄膜的性能最佳，对比光滑DLC薄膜，其耐磨寿命提升了7.52倍。力学表征及仿真分析表明，表面织构增强了DLC薄膜与TC4基体之间的“机械锁合”程度，并存在“应力扩散”现象，能够有效提升DLC薄膜与TC4基体间的力学性能。对比光滑DLC薄膜，织构化DLC薄膜试样涂层与基体之间的结合力最大可提升1.9倍。结论 表面织构化设计可以有效地提升DLC薄膜与基体的力学性能，在摩擦过程中调节接触界面的应力分布，增强DLC薄膜耐磨性能，延长DLC薄膜使用寿命。研究结果将为新型人工关节表面设计提供理论支撑。 |
| 英文摘要: |
| As a crucial medical treatment modality, artificial joint replacement has gained extensive utilization in addressing joint aging and pain. However, the service life of artificial joint pairs is predominantly constrained by the friction and wear characteristics of the material surface. Prolonged usage of artificial joints often leads to loosening and detachment, exacerbating patients' discomfort. The work aims to fabricate a composite structure by integrating surface texture and DLC film onto the titanium alloy surface of artificial joints to investigate their frictional and wear properties. Moreover, the underlying mechanism governing the tribological behavior of DLC film on textured TC4 titanium alloy surfaces will be elucidated, thereby providing theoretical support for innovative design of artificial joint interfaces. |
