Abstract: ［Objective］To address the issues of superhydrophobic coating is prone to loss and thecoating exhibits poor long-term stability under harsh conditions，leading to the attenuation of anti-corrosion and anti-scaling performance and insufficient service durability.［Methods］In this study，a hydrothermal method was adopted to synthesize flower-like structured nano-ZnO particles，which were subsequently subjected to hydrophobic modification with hydroxyfluorosilicone oil. The superhydrophobic coating was fabricated via a spray-coating technique，and then the coating was impregnated with hydroxyfluorosilicone oil to form a super-slippery surface. Scanning electron microscope，contact angle measurement instrument，electrochemical workstation were used to characterize the wettability，wear resistance，chemical stability，corrosion resistance，and anti-scalingperformance of the coating.［Results］The super-slippery surface prepared by coating hydroxyfluorosilicone oil exhibits a water contact angle（WCA）of（132. 9±2. 1）° and a sliding angle of（6. 8±0. 3）° . The corrosion current density（I_corr）of the prepared super-slippery coating was 2. 81×10^-11 A/cm²，and the corrosion potential（E_corr） was -0. 32 V. Furthermore，after dynamic simulated scaling test in a 0. 01 mol/L Ca²⁺ solution for 7 days，the CaCO₃ scaling amount on the surface of the super-slippery coating was only 3. 3 mg/cm².［Conclusion］The coating possesses good mechanical properties and chemical stability，and exhibits excellent anti-corrosion and anti-scaling effects，providing an effective solution to the corrosion and scaling issues of industrial metal materials.

摘要： 【目的】针对超疏水涂层在防腐阻垢过程中表面气膜易流失、长效稳定性差，导致防腐阻垢性能衰减、服役耐久性不足的问题。【方法】采用水热法合成花状结构纳米 ZnO粒子，经羟基氟硅油疏水改性后，以喷涂法制备超疏水聚偏氟乙烯（PVDF）/氟化 ZnO涂层，再通过浸渍羟基氟硅油，得到超滑涂层。通过扫描电子显微镜、接触角测量仪、电化学工作站等，系统分析涂层的润湿性、耐磨性、化学稳定性、耐腐蚀性及阻垢性能。【结果】涂覆羟基氟硅油制得的超滑涂层表面水接触角为（132. 9±2. 1）°，滑动角为（6. 8±0. 3）°。制备的超滑涂层表面腐蚀电流（I_corr）为 2. 81×10^-11 A/cm²，腐蚀电位（E_corr）为-0. 32 V。此外，在 0. 01 mol/L Ca²⁺模拟结垢溶液中进行 7d动态测试，超滑涂层表面 CaCO₃结垢量仅 3. 3 mg/cm²。【结论】该涂层具备良好的力学性能、化学稳定性，展现出优异的防腐阻垢效果，为工业金属材料的腐蚀与结垢问题提供了有效解决途径。
