Abstract:A movel method of preparing the super‐hydrophobic surface on steel was proposed .This method successfully prepared the super‐hydrophobic surface by constructing the micro‐nano Ni‐nSiO2 structures on Q235 .At first ,technique of composite electro‐deposition was improved .Then ,the effect of Ni2+ concentration on super‐hydrophobic property was studied and the most suitable solution formula was obtained by orthogonal test and range analysis .Finally ,the impacts of current density , anode speed and time were analyzed respectively .When the current density is set at 37 .5 A/dm2 , speed of anode is set at 8 m/min ,deposition time is 3 min ,a super‐hydrophobic surface with contact angle 153 .5°and roll angle 6 .5° can be prepared .
