Abstract	The wettability of metal surface is of great interest due to its potential application in academic research and practical application. Researchers fabricated hierarchical structures consisting of micro-flowers and secondary nano-sheets using electrodeposition and solution-immersion process on X90 pipeline steel substrate. The CuO flower-like structures in situ grew on the surface of deposition Cu coating via chemical reactions in the process of solution-immersion, which was similar to the surface morphology of the lotus leaf. After fluorinated modification, the CuO film on the X90 pipeline steel exhibited a fine superamphiphobic, as well as an excellent self-cleaning property. In addition, potentiodynamic polarization measurement indicated that the superamphiphobic CuO film significantly improved the corrosion resistance of the X90 pipeline steel. The superamphiphobic CuO film of the steel substrate surface was achieved by a simple and inexpensive process that was suitable for any shape. This provided new multifunctional applications of deposition metal coating, including superamphiphobic, self-cleaning and corrosion resistance properties.
