中文摘要: 超疏水膜具有良好的防腐蚀性能，能够有效地延长金属制品的使用寿命，提高经济效益.选取白铜作为研究对象，采用化学刻蚀氧化自组装法进行超疏水膜表面的制备.通过交流阻抗和极化曲线法，在模拟海水条件下，利用三电极体系对超疏水表面的耐蚀性能进行了研究和测定.结果表明，所制备的白铜超疏水表面的接触角达到了154°，在3.5%的NaCl溶液中的缓蚀效率有99.1%，具备较高的超疏水性能和耐蚀性能，且其表面具有微纳米级的树枝状结构.
Abstract:The super hydrophobic film has good anti-corrosion property,which can effectively prolong the service life of the metal products and improve economic benefits.Selecting copper-nickel alloy as the research object,and using the chemical etching and self-assembling method to prepare superhydrophobic film on the surface of the copper-nickel.The three electrode system is used to study the corrosion resistance of the superhydrophobic film on the copper-nickel in the method of AC impedance and polarization curve.The results show that the contact angle of achieved copper-nickel alloy superhydrophobic surfaces reaches 154°,the inhibition efficiency at 3.5 wt.% NaCl solution are 99.1%,the surface has a higher super-hydrophobic properties and corrosion resistance,and the surface appears in a large number of vertical chip-like structures with micro-nano scale.
