摘要：

Nano-SiO2 powder was coated on the polished and laser etched surface by the sol-gel and dip-coating method to prepare hydrophobic/superhydrophobic warship aluminium alloy surface. The durability of the hydrophobic/superhydrophobic surface was tested by using the method of the sample load and friction slide on sand paper. The results show that the contact angle of polished surface increases with increasing SiO2 concentration up to 150.8°, but the surface has high adhesive force for the droplet. When the length of sliding reaches 10 m, the contact angle is 72.3° less than the original. The surface fabricated by laser etched grid or dot microstructures exhibits both superhydrophobic and low adhesive force. The grid surface has greater contact angle as high as 155.4°, and smaller roll angle, the minimum is only 0.34°. When the length of sliding reaches 10 m, the surface is still hydrophobic, and the grid microstructure has greater durability. ©, 2014, Cailiao Gongcheng/Journal of Materials Engineering.
