    摘要:

    研究了常規(guī)純鈦和超細晶純鈦陽極氧化表面的形貌、膜-基結合力、抗腐蝕性能和微動摩擦磨損性能。結果表明：與常規(guī)純鈦氧化表面相比，超細晶純鈦氧化表面具有更多納米尺度孔穴，更高的膜-基結合力（后者是前者的2倍），更高的抗模擬體液電化學腐蝕性能（后者的腐蝕速率是前者的2/5），更低的摩擦系數（0.12:0.34）、更高的耐磨性。分析認為，以上性能變化是純鈦組織超細化提高其晶體缺陷（內能）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.
