| 摘 要： | 为了在钢基材料上制备超双疏表面,同时避免破坏钢基表面的物理性质,提出一种采用纳米复合电镀法在船用Q235钢材上制备Ni-nSiO_2超双疏表面的工艺。采用纳米复合电镀和液相沉积法在钢基表面构造适合的超双疏性能的微纳米双层粗糙结构。改变复合电镀参数,得到制备钢基超双疏表面的工艺参数。当电流密度为12.5A/dm^2,磁流搅拌速度为200r/min,电镀时间为50min,温度为60℃时,可制备出与水的接触角为154°,与油的接触角为151°的钢基超双疏表面。

| Abstract: | In order to prepare super amphiphobic surface coating on steel base and to avoid damage to the physical properties of the surface, a method of constructing Ni-nSiO2 super amphiphobic surface on a Q235 steel base is proposed. Through nano composite electroplating and liquid phase deposition method, the micro nano double layer rough structure suitable for super amphiphobic performance are constructed on steel base. The preparation process parameters of the super amphiphobic surface of the steel base are obtained by changing the composite electroplating parameters. When the current density is 12.5 A/dm^2, the magnetic flow stirring speed is 200 r/min, the electroplating time is 50 minutes and the temperature is 60 ℃,the super amphiphobic surface can be prepared with water contact angle of 153° and oli contact angle of 151°. |
