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(Icorr)of the prepared super-slippery coating was 2. 81×10-11 A/cm2,and the corrosion potential(Ecorr) 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.
