Aluminum material is first etched to produce rough structure of micrometer degree , then the anodic treatment by means of phosphoric acid is carried out to prepare the surface structure of micro-nanometer degree ; finally , the superhydrophobic film is prepared by immersing the specimen into the myristic acid. It is found that there is relatively certain relationship between roughness and thickness : however , the relationship with the degree of the hydrophobic effect is not obvious , whenever , the hardness increase with the film thickness . Formerly , the anti-corrosive property of the anodic film is always related between the thickness and between the hardness ; however , after the addition of hydrophobic effect , the anti-corrosive property depends conversely upon the hydrophobic degree . For example , the hardest (327.4Hv) and thickest (4.7?慆) film has a hydrophobic angle of only 140° , a contact area of 26% , and a corrosion current of 7.54E-0.6(A) . However , the highest hydrophobic degree of 154° occurs when the the hardness is 247.2 Hv and film thickness is 2.9?慆 , the contact area between the liquid and specimen surface is only 14% such that the contact chance between the corrosive material and specimen is decreased so as to enhance the anti-corrosive property of the specimen . In addition , by observing the morphology of the specimen by means of SEM , it is discovered that the good hydrophobic surface shows the shape of step field , but when the surface is relatively smooth , the hydrophobic angle drops .
