摘要
针对腐蚀介质对不锈钢表面的点蚀问题,以304L不锈钢为基体,通过复合电沉积方法制备超疏水Ni-MoS_(2)-Al_(2)O_(3)复合镀层,探究不同电流密度对表面形貌、元素含量和润湿性的影响,并与纯镍涂层进行比较。结果表明:当加入MoS_(2)和Al_(2)O_(3)颗粒后,镍的成核过程发生变化,镀层表面含有大量团簇状的微纳米球凸起。在电流密度为8 A/dm^(2)的实验条件下,经过硬脂酸乙醇溶液改性后,接触角的最大值为159.6°,具有良好的疏水性、低附着力和自清洁性。且镀层中MoS_(2)和Al_(2)O_(3)颗粒含量最高,分别为5.6%和7.1%。
In order to solve the pitting corrosion problem of stainless steel in corrosive medium,super‐hydrophobic Ni-MoS_(2)-Al_(2)O_(3)composite coating was prepared by composite electrodeposition on 304L stainless steels.The effects of different current density on the surface morphology,element content and wettability were explored and compared with that of pure nickel coating.The results showed that the nucleation process of nickel changed with the addition of MoS_(2)and Al_(2)O_(3)particles,and the surface of the coating was composed of clusters of micro and nano spheres.The contact angle reached 159.6°at the current density of 8 A/dm^(2)after the coating was modified by stearic acid ethanol solution.And the coating had good hydrophobicity,low adhesion and self-cleaning.The contents of MoS_(2)and Al_(2)O_(3)particles in the coating were the highest,which were 5.6%and 7.1%,respectively.
