摘要: Brass is widely used in machinery, electronic appliances and emerging industries. The corrosion resistance of laser-induced
superhydrophobic surface of brass needs to be improved. In recent years, bionic surface with slippery coating has attracted
much attention because of its excellent corrosion inhibition performance. Here, we fi rst prepared the superhydrophobic
surface of brass by nanosecond laser ablation combined with fl uoroalkyl silane modifi cation, and then injected silicone oil
into the prepared superhydrophobic matrix to obtain a slippery coating surface. PDP and EIS tests in 3.5 wt.% NaCl solution showed that the corrosion resistance of the slippery surface was better than that of the superhydrophobic surface. This
study can play a certain role in promoting the development of metal anticorrosive coating and is of great signifi cance in the
preparation of slippery surface by laser induction, and provides a convenient and eff ective means for metal anticorrosion in
the industrial fi eld.
