摘　　要：利用电沉积方法在DH36船板钢表面备了微纳米结构的锌镍合金镀层。采用扫描电镜(SEM)、(EDS)和X射线衍射仪(XRD)和研究了电化学沉积时间对镀层形貌、化学成分和晶体结构的影响。利用接触角测试仪,研究了锌镍合金镀层的润湿性能在PFTEOS修饰前后随电沉积时间的变化。其中沉积时间为3000 s的微纳米分层结构的锌镍合金镀层,其接触角超过160°,表现为超疏水性。电化学极化曲线测试结果显示,所制备的超疏水锌镍合金镀层的耐蚀性相比于DH36船板钢约提高32倍左右。In this study,the micro-nano structured Zinc-Nickel alloy coating was fabricated on the DH36 ship plate steel.The influence of electrodeposition time on the morphology,chemical composition and crystal structure of the coating was studied by scanning electron microscope(SEM),X-ray energy dispersive spectrometer(EDS)and X-ray diffractometer(XRD).Using the contact angle measurement,the wetting properties of the as-deposited Zinc-Nickel alloy coating with the electrodeposition time before and after PFTEOS modification was studied.The results indicated that the micro-nano structured Zinc-Nickel with deposition time of 3000 s had contact angle of more than 160°,exhibiting the super-hydrophobic properties.And the electrochemical polarization curves confirmed that the corrosion resistance of the as-prepared superhydrophobic Zinc-Nickel alloy coating was about 32 times higher than that of DH36 ship plate steel.
