Fabrication of biomimetic hydrophobic films with corrosion resistance on magnesium alloy by immersion process
Biomimetic hydrophobic films of crystalline CeO2 were prepared on magnesium alloy by an immersion process with cerium nitrate solution and then modified with DTS (CH3(CH2)(11)Si(OCH3)(3)). The CeO2 films fabricated with 20-min immersion yield a water contact angle of 137.5 +/- 2 degrees, while 20-min DTS treatment on top of CeO2 can further enhance the water contact angle to 146.7 +/- 2 degrees. Then corrosion-resistant property of these prepared films against NaCl solution was investigated and elucidated using electrochemical measurements. (C) 2012 Elsevier B. V. All rights reserved.
