| 摘 要： | 为了研究微弧氧化工艺参数对涂层表面形貌的影响以控制表面形貌,用扫描电镜(SEM)和原子力显微镜(AFM)观察了复合氧化法制备的二氧化钛涂层表面形貌,用X射线衍射(XRD)分析了涂层的相结构。SEM观察结果表明,涂层为多孔凹凸不平的表面。AFM观察结果表明,二氧化钛均由nm级颗粒堆垛而成。XRD分析表明,二氧化钛涂层的晶相为锐钛矿、金红石和单质钛。通过对表面粗糙度的计算可知,微弧氧化时间减少可使表面粗糙度降低,涂层具有极大的表面改性潜力。

| Abstract: | The surface morphology of titania coatings prepared by using a composite oxidation method was investigated by using a scanning electrical microscope SEM and an atom force microscope AFM to control the surface morphology of the coatings. X ray diffraction spectra XRD were employed to determine the phase configurations of the coatings. The results show that the coatings all have uneven porous surfaces that are grain-packed under AFM nm degree in appearance. The phases in the titania coatings are anatase, rutile, and titanium. The roughness of the coatings decreases with decreasing working time of micro-arc oxidation. The coatings provide great potential for useful surface modification in a variety of fields. |
