Abstract:
This disclosure relates to a method for obtaining superhydrophobic corrosion-resistant coatings. State-of-the-art approaches involve etching methods with elevated temperatures and/or longer duration which are complex and use high concentration of combination of acids, alkali, and salt solutions in etching process to obtain a roughness which makes it difficult to handle usage of chemicals and controlling process. The method of the present disclosure has addressed this issue by selection of optimum concentrations of combinations of one or more type of acids, oxidizing agents which are safe, easy to handle and provide better control over the process. The method of the present disclosure is easy, inexpensive, and environmentally friendly. The superhydrophobic corrosion-resistant coatings possess water contact angles greater than 151° and coating efficiency more than 85 percent arrived at by using corrosion currents from polarization studies.
