In this paper, we introduced an advanced discussion of the 3D morphology of TiO2 coatings deposited on ITO substrate by electrodeposition, under different deposition times. Atomic force microscopy was applied for obtain topographic images of the samples. The images were processed using the MountainsMap 8.0 commercial software according to ISO 25178-2:2012. Moreover, fractal theory was applied to study the surface microtexture of coatings. The morphology was affected by the deposition time, where the grain size decreased according to the increase of the time, making film's surfaces smoother. In addition, the surface roughness exhibited a random behavior, but does not presented significant difference between samples. The fractal dimension showed similar values for all coatings. In contrast, surface texture isotropy also exhibited random behavior. However, advanced fractal parameters revealed that when the deposition time increased the coatings microtexture has become uniform and less porous. Furthermore, all coatings presented high topographic uniformity, regardless of deposition time. These results revealed that the morphology and microtexture of TiO2 based coatings can be controlled by the deposition time. This article is protected by copyright. All rights reserved.

电沉积ITO基底上TiO 2 涂层的纳米级形貌和分形分析

在本文中，我们介绍了在不同沉积时间下通过电沉积在 ITO 基板上沉积的 TiO2 涂层的 3D 形态的高级讨论。应用原子力显微镜来获得样品的形貌图像。根据 ISO 25178-2:2012 使用 MountainsMap 8.0 商业软件处理图像。此外，分形理论被应用于研究涂层的表面微观结构。形态受沉积时间的影响，其中晶粒尺寸随着时间的增加而减小，使薄膜表面更光滑。此外，表面粗糙度表现出随机行为，但在样品之间没有表现出显着差异。所有涂层的分形维数显示出相似的值。相比之下，表面纹理各向同性也表现出随机行为。然而，先进的分形参数表明，当沉积时间增加时，涂层微观结构变得均匀且孔隙较少。此外，无论沉积时间如何，所有涂层都呈现出高的形貌均匀性。这些结果表明，TiO2 基涂层的形貌和微观结构可以通过沉积时间来控制。本文受版权保护。版权所有。
