Superamphiphobic surfaces on titanium alloy substrates were successfully fabricated via one-step anodization and subsequent fluoroalkylsilane modification. The prepared superamphiphobic titanium alloy surfaces display contact angles with water, glycerol and hexadecane are 166.4 degrees +/- 1.8 degrees, 158.4 degrees +/- 2.1 degrees and 152.5 degrees +/- 1.9 degrees, respectively, corresponding sliding angles are all within 10 degrees, which can be attributed to the combination of reentrant micro/nano structures with low surface energy modification. In order to obtain the optimal superamphiphobicity, the relationship between reaction time with wettability of the superamphiphobic surfaces is analyzed in detail. Furthermore, the robustness of the superamphiphobicity is also investigated by UV light test, immersion test and abrasion test, which show that the created superamphiphobic surfaces possess good stability under harsh conditions. The developed approach is simple and has potential to be applied into the commercial production of large-area superamphiphobic titanium alloy surface. (C) 2014 Elsevier B.V. All rights reserved.
