Abstract
The main objective of the present work is to check the durability of superhydrophobic aluminium alloy by using an adhesive peel, sandpaper abrasion and water impact test. Chemical etching and dip-coating methods are used to fabricate the superhydrophobic aluminium surfaces. It is observed that the water contact angle decreases with the increase in number of cycles in adhesive peel, sand abrasion test and with an increase in time in a water impact test. It is also observed that the fabricated superhydrophobic samples sustained its characteristics up to 20 cycles in adhesive peel test, 15 cycles in sand abrasion test and 4 min in water impact test. Further, in order to enhance the oleophobic characteristics, the surface formed after the treatment by immersing in boiling water shows oleophobic characteristics as well. It is found that the contact angle formed by glycerol and water droplet on the surface is 110.56° and 150.13°, respectively.
