Preparation of wear-resistant superhydrophobic EP/PF@SiO2 composite coating on Mg alloy with excellent corrosion resistance
Source abstract
Abstract
Superhydrophobic coatings have been widely studied for their ability to reduce the contact area and contact time between the anti-corrosion coating and the corrosive environment due to their excellent water-repellent properties. However, the wear resistance of such coatings has received limited attention. In this work, a novel wear-resistant superhydrophobic composite epoxy resin coating was developed by embedding superhydrophobic nano-SiO2 particles into the matrix. The resulting coating shows a high water contact angle of 158° and a low rolling angle of 1°, indicating excellent superhydrophobicity. Ever after undergoing a 7 m friction test under the pressure of 2.45 kPa, the WCA remained as high as 154°, demonstrating superior mechanical durability. Electrochemical test results revealed a reduction in corrosion current density (icorr) by 5 orders of magnitude compared to bare Mg alloy. This work provides promising for the design of wear-resistant superhydrophobic composite coatings with enhanced corrosion resistance for magnesium alloy surfaces.
