摘要

为延长镁合金的使用寿命,使用喷涂法在AZ31b镁合金基体上制备出稳定的超疏水涂层。首先在基体表面涂覆环氧树脂粘结层,向其喷涂微米SiO2颗粒,以构建微米级框架,紧接着喷涂纳米聚四氟乙烯颗粒,以提供疏水性粒子。所制备的超疏水涂层接触角约为157.40°,滚动角仅为2°。试验结果表明:该超疏水涂层具有优异的化学与机械稳定性,良好的耐腐蚀性能以及自清洁、防污特性。

Abstract

In order to prolong the service life of magnesium alloy, a stable superhydrophobic coating was prepared on AZ31b magnesium alloy substrate by spraying method. Firstly, an epoxy resin bonding layer was coated on the surface of substrate, and micron SiO2 particles were sprayed on the epoxy resin bonding layer to construct a micron framework. Subsequently, nano polytetrafluoroethylene particles were sprayed to provide hydrophobic particles. The prepared superhydrophobic coating had a contact angle of ~157.40° and sliding of only 2°. Results showed that the superhydrophobic coating had excellent chemical and mechanical stability, good corrosion resistance, self-cleaning and anti-fouling properties.
