Scaling is a universal issue encountered in pipeline steel during offshore oil extraction. In this paper, a synergic anti-scaling Cu-Zn-CeO2 coating on the pipeline steel substrate was fabricated by one-step composite electrodeposition and magnetic stirring. It shows the wettability transition from superhydrophilic to superhydrophobic of the multi-scale structured Cu-Zn-CeO2 coating without low-surface-energy modification after heating at 60℃ for 60 min and stored in air for ∼ 35 days. The wettability transition is owing to the hydrocarbons adsorption. The heating treatment and the multi-scale structure improve the hydrocarbons adsorption and reduce the transition time. The inherent hydrophobic CeO2 is beneficial for the superhydrophobic property and reduces the transition time. Compared with the steel substrate and previous superhydrophobic Cu and Cu-Zn coatings, it indicates the superhydrophobic Cu-Zn-CeO2 coating shows the promising synergic anti-scaling property due to its superhydrophobicity and the anti-scaling property of Cu-Zn alloys. This eco-friendly synergic anti-scaling Cu-Zn-CeO2 coating also shows excellent self-cleaning and anti-fouling properties. Moreover, the stability of the superhydrophobic Cu-Zn-CeO2 coating was enhanced compared with our previous superhydrophobic Cu-Zn coating due to CeO2 nanoparticles. This research enriches the theory and the technology of the wetting field, which also provides a technical basis for solving scaling problems of pipelines.
