Robust and anti-corrosive PDMS/SiO 2 superhydrophobic coatings fabricated on magnesium alloys with different-sized SiO 2 nanoparticles
Abstract(#br)In this work, micro-nanostructure polydimethylsiloxane/silicon dioxide (PDMS/SiO 2 ) composite coatings were fabricated on the surface of magnesium alloys with two different sizes of SiO 2 nanoparticles by a simple painting method. The effects of the proportion of 40 nm and 50–250 nm SiO 2 on the wettability, wear and corrosion performance of the composite coatings were investigated.
