将钛基材在700~1000℃进行渗碳处理后利用热分解法制备了30%RuO2-70%TiO2涂层电极。采用X射线衍射、扫描电镜分析观察渗碳温度对钛基体和涂层组织结构的影响,并通过循环伏安和强化寿命研究了电极的电化学活性和稳定性。结果表明,随着渗碳处理温度的升高,钛基体表面的组织结构发生变化,从而改变了涂层的微观结构,也显著影响了电极的电催化活性和耐蚀性。
After carburizing titanium substrate at 700 ~ 1000 ℃, 30% RuO2-70% TiO2 coated electrode was prepared by thermal decomposition method. The effects of carburizing temperature on microstructure and structure of titanium matrix and coating were observed by X-ray diffraction and scanning electron microscopy. The electrochemical activity and stability of the electrode were studied by cyclic voltammetry and lifetime enhancement. The results showed that with the increase of carburizing temperature, the microstructure of the titanium substrate changed, which changed the microstructure of the coating and significantly affected the electrocatalytic activity and corrosion resistance of the electrode.
