摘要

为了在提高钛合金表面性能的同时,又可赋予其多彩的外观或实现消光等目的,利用直流脉冲稳压电源在不同氧化电压下制备钛合金阳极氧化膜。采用化学浴沉积法在钛合金阳极氧化膜层表面沉积适量羟基氧化铁(FeOOH)颗粒,研究FeOOH 对钛合金阳极氧化膜层光学及半导体性能的影响。采用扫描电镜(SEM)、X 射线衍射仪(XRD)、EDS、电化学工作站分析测试了氧化膜及复合FeOOH 后膜层的形貌、物相、元素组成、光电流密度、电化学阻抗和Mott-Schottky 曲线。结果表明:在电压为40 V 时,钛合金阳极氧化膜具有优异的光学及半导体性能。在40 V 电压下生长的阳极氧化膜表面复合FeOOH 可显著提高其光电流密度,使其电荷转移电阻明显减小,迁移速度变得更快,光学性能得到明显改善。

Abstract

For improving the surface properties of titanium alloys while also giving them a colorful appearance or achieving extinction,the anodized films on titanium alloy were prepared by using DC pulse stabilized power supply under different oxidation voltages.Subsequently,a chemical bath deposition method was used to deposit an appropriate amount of FeOOH particles on the surface of the titanium alloy anodized films,and the effect of FeOOH on the optical and semiconductor properties of the titanium alloy anodized films were analyzed.Scanning electron microscope (SEM),X-ray diffractometer (XRD),EDS,and electrochemical workstation were used to study and test the morphology,physical phase,elemental composition,photocurrent density,electrochemical impedance and Mott-Schottky curves of the oxide films with and without FeOOH.Results showed that the anodic oxide film on titanium alloy had excellent optical properties and semiconductor properties,when the voltage was 40 V.The FeOOH on the surface of the anodic oxide film obtained at 40 V could significantly increase its photocurrent density,and significantly reduce its charge transfer resistance,which could weaken the charge transfer resistance,accelerate the migration speed,and improve the optical properties obviously.
