摘　　要：通过阳极氧化处理技术在钛表面制备出具有不同粗糙度和亲水性的纳米表面。采用扫描电镜观察表面特征,原子力显微镜检测表面粗糙度,接触角仪测量亲水性。实验结果表明,表面形貌随着氧化电压和时间的改变有较大变化。在优化的电解液和氧化条件下,可以在钛表面制备规则排列的纳米管阵列。粗糙度随着氧化时间的延长而增大,在几十到几百纳米之间变化,而氧化电压对粗糙度的影响不大。表面亲水性随着氧化时间的延长先增加再降低。钛表面结构形貌、粗糙度与亲水性的变化可用阳极氧化过程中表面发生的反应进行解释。Anodic oxidation was applied to prepare the nanostructured titanium surface with different roughnesses and hydrophilicities. The morphology was characterized by scanning electron microscopy（SEM）. The surface roughness was tested by atomic force microscopy（AFM）, and the hydrophilicity was assessed from the contact angle between the deionized water and sample surface at room temperature. The results show that surface morphologies change remarkably with applied voltage and oxidation time during anodic oxidation. Under optimized oxidation conditions, well-ordered nanotube arrays were fabricated on the Ti surface. Roughness values increase with increase of the oxidation time, ranging from several dozen to several hundred nanometers, while the influence of voltage on surface roughness is not obvious. The hydrophilicity increases initially with the increase of oxidation time, but then decrease. The variations of surface morphology, roughness and hydrophilicity are correlated to the reactions occurring during the anodic oxidation.
