Abstract

Zinc-nickel (ZN) coatings were deposited on N80 steel substrates using pulsed electrodeposition. The current density of the two-step electrodeposition process was adjusted to promote the formation of micro/nanostructures on the coating surface. Superhydrophobic coatings were obtained by using appropriate current parameters and subsequent modification of the coatings with hexadecyltrimethoxysilane. The results showed that the coating achieved a water contact angle of 157 ± 1° and a sliding angle of 6 ± 1°, indicating that the superhydrophobicity was successfully constructed. In addition, electrochemical tests confirmed the coating’s excellent corrosion resistance. Compared with other samples, the corrosion current density of the coating in 3.5 wt% NaCl solution was significantly reduced, the corrosion inhibition rate reached 94.41%, and the impedance modulus in the low-frequency region of the Bode plot was improved by one order of magnitude compared with that of the blank sample. In conclusion, the prepared superhydrophobic coating has good hydrophobicity and corrosion resistance and has a broad industrial application prospect.

电沉积 Zn-Ni-HDTMS 涂层的超疏水性和耐腐蚀性研究

采用脉冲电沉积法在 N80 钢基底上沉积锌镍（ZN）涂层。调整了两步电沉积过程的电流密度，以促进涂层表面微/纳米结构的形成。通过使用适当的电流参数以及随后用十六烷基三甲氧基硅烷对涂层进行改性，获得了超疏水涂层。结果表明，涂层的水接触角为 157 ± 1°，滑动角为 6 ± 1°，表明超疏水涂层已成功构建。此外，电化学测试也证实了涂层优异的耐腐蚀性能。与其他样品相比，涂层在 3.5 wt% NaCl 溶液中的腐蚀电流密度明显降低，腐蚀抑制率达到 94.41%，Bode 图低频区的阻抗模量与空白样品相比提高了一个数量级。总之，制备的超疏水涂层具有良好的疏水性和耐腐蚀性，具有广阔的工业应用前景。

期刊介绍： The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
