Facile and low-cost method to fabricate a superhydrophobic aluminum alloy surface: towards optimum preparation conditions

نوع فایل:PDF تعداد صفحات :5 سال انتشار : 1394 چکیده Aluminum and the aluminum alloys are important and useful materials in industry with potential for enhanced applications via creating novel properties such assuperhydrophobicity and self-cleaning features. In this study, an improved facile and low-cost surface treatment approach was developed to create a superhydrophobicaluminum surface. Overall, the modified aluminum substrates exhibited a satisfactory superhydrophobicity, with a static water contact angle of about 1461 and a contact angle hysteresis of approximately 11. The effects of two key parameters including theetching time and coating temperature were investigated using simple and handy measurement techniques. The results show that a 4 min...
