Abstract Al2O3 and Ti-doped Al2O3 nanocomposite ceramic coatings were prepared by using a sol-gel dip-coating process. Corrosion and wear resistance of Al2O3 ceramic coatings in relation to Ti amount were carried out using pin-on-disk tribotester, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Surface characterizations before and after the corrosion and wear tests were investigated by the scanning electron microscope (SEM) and X-ray diffraction (XRD) and hardness analysis. The results of corrosion and wear tests exhibited that the corrosion and wear resistance of nanocomposite ceramic coatings became better than uncoated samples. Also, corrosion and wear resistance of nanocomposite ceramic coatings improved with Ti doping content increased.

Ti含量对掺TiAl 2 O 3 纳米复合陶瓷涂层CP钛植入材料磨损和腐蚀性能的影响

摘要 采用溶胶-凝胶浸涂工艺制备了Al2O3和Ti掺杂Al2O3纳米复合陶瓷涂层。使用pin-on-disk tribotester、动电位极化和电化学阻抗谱（EIS）对Al2O3陶瓷涂层的耐腐蚀性和耐磨性与Ti含量进行了比较。通过扫描电子显微镜（SEM）和X射线衍射（XRD）以及硬度分析研究腐蚀和磨损试验前后的表面表征。腐蚀磨损试验结果表明，纳米复合陶瓷涂层的耐腐蚀性和耐磨性优于未涂层样品。此外，随着Ti掺杂量的增加，纳米复合陶瓷涂层的耐蚀性和耐磨性得到提高。
