摘要：Composite brush plating technique was used to prepare superhydrophobic n-SiO2/Ni brush plating composite coating on Q235 steel surface. Under the better process parameters, the water contact angle of the obtained super-hydrophobic surface was approximately 169.8��, and the water tilting angle was approximately 2.3��. This paper gave the influences of plating voltage and plating time on the coating surface structure and hydrophobicity, and gave the effects of the moving velocity of brush on the content of n-SiO2 of the composite coating. The structure and morphology of the composite coating surface and its section were also studied. The measurements of the contact angle, surface roughness and microhardness of the coating were carried out. Results show that the plating voltage and plating time are two important parameters for the composite coating surface microstructure characteristics. And the binary micro-nano structure on composite coating surface plays an important role in super-hydrophobic property.
