| 摘 要： | 文中主要研究了纯钛、Ti6A17Nb基体以及经过氮离子注入后的改性层的扭动微动磨损行为.氮离子注入采用高能离子注入机及增强沉积系统,加速电压为50 kV,注入剂量分别为1×l017、5×1017和9×1017cm-2.采用球/平面接触模式,对纯钛和Ti6Al7Nb合金/(Zr2O球(直径为25.2 mm),接触副在小牛血清介质条件下进行了纯钛和Ti6Al7Nb合金及其改性层的了扭动微动磨损试验.借助X衍射仪(XRD)、拉曼光谱(Raman)、三维形貌仪(3D)和扫描电镜(SEM)分析了两种材料及其改性层的化学成分、微动磨损磨痕形貌和微观组织结构,探讨了纯钛和Ti6Al7Nb合金基材和改性层的扭动微动运行行为和损伤机制.研究结果表明:用氮离子注入方法处理钛及其合金,生成的氮化物层能够改善材料表面的综合性能,提高其扭动微动磨损的耐磨性.纯钛和Ti6Al7Nb基体的磨损现象为氧化和剥落,其离子注入层的磨损现象为犁沟. |

| Abstract: | Pure titanium and Ti6Al7Nb alloys alloys were implanted by 50 keV N+ ions with different implanting dosage in high energy ion implantation and enhanced deposition system. Torsional fretting wear of un-treated and plasma implantation nitride titanium alloys flats against ZrO2 ball (with a diameter of 25.2 mm) were carried out under a simulated physiological condition. With analyses of the frictional kinetics behaviors, the X-ray diffraction, Raman spectroscopy, 3-D profiler,SEM morphologies, the damage characteristics of the surface modification layer and its substrate were discussed in detail.The results show that the plasma implantation nitride can improve its surface properties and the resistance of torsional fretting wear can be improved obviously.The wear mechanism of the pure titanium and Ti6Al7Nb were oxidation wear and delaminlation, the ploughing of the modification layers. |
