Abstract
The development of non-wax-stick coating is an important issue for petroleum industry. In this letter, an excellent non-wax-stick coating was prepared based on Zn coating by chemical conversion treatment. The chemical conversion coating had hydrophilic and superoleophobic properties in water/oil mixture system, which enabled it to trap water molecules on the surface and reduce wax deposition. The coating was mainly composed of Zn and O elements accompanied by some Si element, and the costing surface showed round bulge structure with different sizes. The combination of chemical composition and structure was considered to play the key role in the special liquid wettability and non-wax-stick properties.
