摘    要:通过化学刻蚀法和自组装技术,构建了白铜的超疏水表面.利用接触角测试和电化学分析技术探讨了制备工艺对疏水膜性能的影响.对不同刻蚀条件下制备的超疏水表面的电化学测试结果进行比较,结果表明:合适的表面粗糙结构是制备具有优良耐蚀性能的超疏水膜的关键.接触角测量和电化学测试结果表明:构建的白铜基超疏水表面的接触角可达152.8°,该超疏水膜能够大幅提高白铜在3.5%NaCl溶液中的耐蚀性能,缓蚀效率达到96.1%.

关 键 词:白铜  超疏水膜  化学刻蚀  自组装  耐蚀性

Abstract:Super-hydrophobic surface has been considered a new and promising anti-corrosion technology recently.A super-hydrophobic film has been fabricated on Cu-Ni alloy(B30) substrates by chemical etching and self-assembly.The effects of etching process and self-assembly technology on the property of filmed B30 had been investigated by means of contact angle measurement and electrochemical test.The results show that suitable surface roughness played a vital role in preparing super-hydrophobic surface with excellent corrosion resistance in comparison with the electrochemical test results of different hydrophobic B30 surface.Moreover,the results indicated that the corrosion resistance of B30 in 3.5%NaCl solution could greatly improved by the super-hydrophobic surface (contact angle 152.8°),and the inhibition efficiency reached 96.1%.
Keywords:Cu-Ni alloy  super-hydrophobic film  chemical etching  self-assembly  corrosion resistance
