摘　　要：采用液相沉积的方法在304不锈钢基体上制备了纳米TiO2薄膜材料,采用XRD、SEM等手段研究了不同沉积时间、不同热处理工艺对薄膜微观结构的影响,采用IM6e工作站研究了薄膜材料的光电化学行为.研究表明,沉积时间为72 h、热处理温度为500℃时,TiO2薄膜具有均匀平整的微观形貌,薄膜主要由锐钛矿TiO2组成.经过热处理的薄膜材料在光照下于模拟海水电介质中均表现出了对304不锈钢的光生阴极防护作用.The nanoscale TiO2 thin films have been successfully fabricated by liquid phase deposition(LPD) method.The microstructure,morphology,and phase composition were investigated through Scanning Electronic Microscopy(SEM) and X-ray Diffraction Patterns(XRD) method.The photoelectronchemical properties,such as polarization curves,variations of open-circuit potential function with time in presence and absence of simulated solar light(metal halogen lamp) were studied.The experimental results showed that anatase coul...
