As a promising material for petroleum industrial applications, titanium (Ti) and its alloys receive wide attention due to their outstanding physicochemical properties. However, the harsh industrial environment requires an antifouling surface with a desired corrosion resistance for Ti and its alloys. In order to achieve the desired antifouling properties, micro-arc oxidation (MAO) was used to prepare a Cu-doped TiO coating. The microstructure of the Cu-doped TiO coating was investigated by TF-XRD, SEM, and other characterization techniques, and its antifouling and anticorrosion properties were also tested. The results show the effects of the incorporation of Cu (1.73 wt.%) into TiO to form a Cu-doped TiO, namely, a Ti-Cu coating. The porosity (4.8%) and average pore size (0.42 μm) of the Ti-Cu coating are smaller than the porosity (5.6%) and average pore size (~0.66 μm) of Ti-blank coating. In addition, there is a significant reduction in the amount of SRB adhesion on the Ti-Cu coating compared to the Ti-blank coating under the same conditions, while there is little difference in corrosion resistance between the two coatings. There, the addition of copper helps to improve the fouling resistance of TiO coatings without compromising their corrosion resistance. Our work provides a practical method to improve the antifouling function of metallic Ti substrates, which could promote the application of Ti in the petroleum industry.
作为石油工业应用中一种很有前景的材料，钛（Ti）及其合金因其优异的物理化学性能而受到广泛关注。然而，恶劣的工业环境要求钛及其合金具有具有所需耐腐蚀性的防污表面。为了实现所需的防污性能，采用微弧氧化（MAO）制备了铜掺杂TiO涂层。通过TF-XRD、SEM等表征技术研究了铜掺杂TiO涂层的微观结构，并测试了其防污和防腐性能。结果表明，将铜（约1.73 wt.%）掺入TiO中形成铜掺杂TiO（即Ti-Cu涂层）的效果。Ti-Cu涂层的孔隙率（约4.8%）和平均孔径（约0.42μm）小于Ti空白涂层的孔隙率（约5.6%）和平均孔径（约0.66μm）。此外，在相同条件下，与Ti空白涂层相比，Ti-Cu涂层上SRB的附着量显著减少，而两种涂层的耐腐蚀性几乎没有差异。因此，铜的添加有助于提高TiO涂层的抗污性能，而不影响其耐腐蚀性。我们的工作提供了一种提高金属钛基体防污功能的实用方法，这可能会促进钛在石油工业中的应用。
