Modern industrial fluid processing vessels and fluid transportation conduits at both the small- and large-scale require durable coatings with well-defined wetting properties at nearly every stage. The same is true of the Alberta energy industry where amphiphobic coatings can be used to mitigate fouling and corrosion. Currently available superhydrophobic coatings suffer from too many crippling inadequacies to merit serious consideration for tackling a large number of industry technical problems. As the premier supplier of process chemistries and water treatment solutions to the Alberta energy industry, NalcoChampion Canada (henceforth called NCC in this grant application) recognizes the need for durable, liquid repellent surfaces. A specific problem of immediate relevance faced by NCC and its clients, relates to the fast corrosion of overhead piping in crude oil distillation. Titania nanotube-based superhydrophobic coatings developed by the Shankar Group at the UofA, offer a potential solution to this problem due to their resilient wetting behavior, corrosion resistance and impressive mechanical properties. The TiO2 nanotubes in such omniphobic coatings are grown on native Ti substrates by the electrochemical anodization process. However the formation of titania nanotubes on non-native, industrially relevant substrates such as carbon steel, presently involves one titanium vacuum deposition step before anodization that is mass producible or scalable. We propose to solve this problem by examining methods of forming TiO2 nanotubes on carbon steel and other industrial substrates, without the use of vacuum deposition.

现代工业流体处理容器和小型和大型流体输送管道 需要几乎在每个阶段都具有良好润湿性能的耐用涂层。也是如此 阿尔伯塔能源行业，其中双疏涂料可用于减轻结垢和腐蚀。目前 现有的超疏水涂层存在太多严重的不足， 解决大量行业技术难题的考虑。作为过程的首要供应商 阿尔伯塔能源行业的化学品和水处理解决方案，加拿大纳尔科冠军（以下简称 在本授权申请中称为NCC）认识到需要耐用的、液体排斥表面。特定 NCC及其客户面临的一个直接相关问题是架空管道的快速腐蚀 在原油蒸馏中。由Shankar集团开发的基于二氧化钛纳米管的超疏水涂层， UofA由于其弹性润湿行为、耐腐蚀性 和令人印象深刻的机械性能。这种全憎涂层中的TiO2纳米管生长在天然纳米管上。 钛基板的电化学阳极氧化过程。然而，二氧化钛纳米管的形成， 非天然的、工业上相关的基材如碳钢，目前涉及一种钛真空 在阳极化之前的沉积步骤，其是可批量生产的或可缩放的。我们建议解决这个问题， 研究在碳钢和其他工业基底上形成TiO 2纳米管的方法，而不使用 真空沉积。
