摘要：

In this work, magnetic Fe3O4 nanoparticles treated with hexadecyltrimethoxysilane were used as immobilization material. Under the anchor of dopamine, the magnetic nanoparticles can be easily deposited on the solid substrate. Array structure was formed by the coated Fe3O4 on the magnesium alloy with the magnet-induced assembly technique. The hierarchical rough surfaces on the substrates form a superhydrophobic coating with a water contact angle as high as 157 degrees. Of note is that the coating significantly decreased the corrosion rate compared with the pristine magnesium alloy in 3.5 wt.% NaCl solution. (C) 2015 Elsevier B.V. All rights reserved.
