| 摘 要： | 研究了常规纯钛和超细晶纯钛阳极氧化表面的形貌、膜-基结合力、抗腐蚀性能和微动摩擦磨损性能。结果表明:与常规纯钛氧化表面相比,超细晶纯钛氧化表面具有更多纳米尺度孔穴,更高的膜-基结合力(后者是前者的2倍),更高的抗模拟体液电化学腐蚀性能(后者的腐蚀速率是前者的2/5),更低的摩擦系数(0.12:0.34)、更高的耐磨性。分析认为,以上性能变化是纯钛组织超细化提高其晶体缺陷(内能)所致。

| Abstract: | The surface morphology, the film-substrate bonding force, the corrosion resistance and the fretting friction and wear properties of anodic oxidized surface of conventional Ti and ultrafine-grained Ti were investigated. The results show that compared to the anodic oxidized surface of conventional Ti, the anodic oxidized surface of ultrafine-grained titanium exhibits a more nano-scale cavities, a higher film-substrate bonding force (bonding force of the latter is 2 times of the former), a higher corrosion resistance (corrosion rate of the latter is 2/5 of the former), a lower friction coefficient (0.12 vs 0.34) and a higher wear resistance. It is believed that these above mentioned improvements are caused by the increasement of crystal defects (internal energy) due to microstructure ultrafinement. |
