An AA-7475 is coated with superhydrophobic (SH) polymer nanocomposites (PNCs), emphasizing the coating’s manufacturing, characterization, and anticorrosive qualities. Coating AA-7475 alloy with polyvinyl chloride (PVC), copper stearate (CS), and zirconium oxide (ZrO₂) nanoparticles produces the desired superhydrophobic. Using an X-ray diffractometer, field-emission scanning electron microscopy, Fourier-transform infrared spectrometer, ZrO₂ nanoparticles, CS, and PVC PNCs are analyzed structurally and molecularly. The atomic force microscope picture was analyzed to determine how the surface roughness affected the SH behavior reached by changing the weight percentage of ZrO₂ nanoparticles from 0.6 to 3.0 wt%. PNC-5 with 3.0 wt% ZrO₂ nanoparticles is used as resistance to corrosion coating for AA-7475 due to its water contact angle of 154°. In a 3.5% NaCl solution, uncoated and PNC-5-coated AA-7475 are examined using potentiodynamic polarization and electrochemical spectroscopy. PNC-5 coating reduces AA-7475 corrosion rate from 23.75 to 0.2253 mpy. In this study, we use polarization resistance, corrosion resistance efficiency, double layer capacitance, corrosion current density, and charge transfer resistance to demonstrate that the SH surface air trapping phenomena are responsible for effective corrosion resistance.

AA-7475/ZrO2/聚合物纳米复合材料的表征及超疏水防腐涂层

AA-7475 涂有超疏水 (SH) 聚合物纳米复合材料 (PNC)，强调了涂层的制造、表征和防腐质量。用聚氯乙烯 (PVC)、硬脂酸铜 (CS) 和氧化锆 (ZrO ₂ ) 纳米粒子涂覆 AA-7475 合金可产生所需的超疏水性。使用 X 射线衍射仪、场发射扫描电子显微镜、傅里叶变换红外光谱仪，对 ZrO ₂纳米粒子、CS 和 PVC PNC 进行了结构和分子分析。分析原子力显微镜图片以确定表面粗糙度如何影响通过将 ZrO ₂纳米颗粒的重量百分比从 0.6 重量百分比改变到 3.0 重量百分比而达到的 SH 行为。_{含有 3.0 wt% ZrO 2}的 PNC-5由于其水接触角为 154°，纳米粒子被用作 AA-7475 的耐腐蚀涂层。在 3.5% NaCl 溶液中，使用动电位极化和电化学光谱检查未涂层和 PNC-5 涂层的 AA-7475。PNC-5 涂层将 AA-7475 腐蚀速率从 23.75 降低到 0.2253 mpy。在这项研究中，我们使用极化电阻、耐腐蚀效率、双层电容、腐蚀电流密度和电荷转移电阻来证明 SH 表面空气捕获现象是有效耐腐蚀的原因。
