激光构筑槽棱与网格状结构超疏水耐腐蚀表面研究
Fabrication of Groove and Grid Structure Surface with Superhydrophobicity and Corrosion Resistance by Laser
摘要
Abstract
With the method of laser processing,the groove and grid structure were constructed on the surface of aluminum alloy which showed the properties of superhydrophobicity and corrosion resist-ance.The features of the material surfaces were characterized by using scanning electron microscope (SEM),laser scanning confocal microscopy(LSCM),X-ray diffractometer(XRD),energy dispersive spectrometer(EDS),water contact angle measurements and polarization curves measurements,re-spectively.The results indicate that the groove and grid structure,which are formed by alternating ablation,show grooves,granular bumps and a pit texture and other composite structures and mor-phologies;the grid structure under the line spacing of 200μm shows excellent hydrophobic properties, and the static contact angle can reach up to 154.9°and the sliding angle is 7°.The analysis on Tafel curve and the curve's fitting results show that the method of laser processing make the groove and grid structure a better corrosion resistance,and the grid structure under the line spacing of 100μm is the best among in these structures.关键词
