Abstract:For solving the difficulties of fabricating large-area superhydrophobic
   aluminum(Al) surfaces,an electrochemical machining technology with a
   small-area moving cathode and fluorination method were proposed.With
   scanning electron microscope(SEM),energy dispersive
   spectroscopy(EDS),and optical contact angle meter,the
   microstructures,compositions,and hydrophobicity of the samples were
   analyzed.The results show that it is feasible to fabricate the
   large-area superhydrophobic Al surfaces with the small-area moving
   cathode.When neutral NaCl electrolyte is used,the effect of the removal
   rate on the hydrophobicity of the Al surfaces at a constant removal mass
   per unit area is small,which is conductive to the high-efficiency
   machining of the superhydrophobic surfaces.The combination of the
   suitable binary micro-nano-meter scale rough structures and the low
   surface energy coating is responsible for the superhydrophobicity of the
   resultant Al surfaces.
